Look! It’s a sandwich! I almost never share sandwich recipes but I needed a change of pace. I’ve been sharing a lot of bowl recipes and I love them all but sandwiches are pretty great too! This charming, stacked cheese sandwich feels so perfect for these springtime days.
I’m in LA this week and this sandwich feels very LA with all the sprouts plus avocado layered inside. It’s so delish!
Yes, it’s rare that I share sandwich recipes, but it’s not that I don’t love a good sandwich, because I really do. It’s more the fact that I have a hard time photographing them. I knew I needed to push all my fears aside when I had this idea because this sandwich is fun and different!
I wanted to create something quick to put together, colorful, and vegetarian. A sandwich where the cheese and veggies are the focus.
Here are details
Start with the bread. Use a loaf of sourdough or rye, something with a little flavor of its own.
Now make that mayo. I love to use an avocado oil mayo. Mix it together with hot sauce, chipotle, and smoked paprika. It’s such a simple creamy sauce but has such yummy flavor.
We’re so into this spicy mayo sauce right now. It’s spicy, but not overpowering. It really adds something special to the sandwich. The smoked paprika is key so don’t skip that.
Ok, now it’s time to assemble. Switch the broiler to high. Layer the bread with the spicy mayo, Havarti cheese, and sliced cherry tomatoes. I like to season the tomatoes with salt and pepper. Then throw the pan in the oven to get the cheese melted and the tomatoes charred.
This only takes a few minutes – watch closely, as the broiler cooks fast.
Now, working quickly (you want the cheese to stay warm). Layer on sun-dried tomatoes, pickles and/or pepperoncini. Add a big hand full of sprouts, avocado, and if you’d like, some pickled onions.
Then I usually add a drizzle more of spicy mayo and finish with the top piece of bread.
Slice and eat! The sandwich is best when the cheese is warm and melty. Add some mayo on the side and go all out and enjoy with your favorite chips. I feel like chips really round out the sandwich experience.
So yummy! I love all the colors, the flavors, and the ingredients hidden within this stacked-up veggie cheese sandwich!! I’m thinking I need to start sharing more sandwich recipes. This one is so fun!
I will say, if you prefer to add meat, roasted chicken or deli-cut turkey would certainly be delicious.
Oh, and a little bacon added on would be amazing too!

Instructions
- 1. To make the mayo. Mix all ingredients in a bowl and season with salt. 2. To make the sandwich, preheat the broiler to high. 3. Working on a sheet pan, spread the outside of each piece of bread lightly with butter. Spread the inside with spicy mayo. Place the cheese slices over the mayo, then add the tomatoes – cut side up.

Hi Tieghan, can you or your team not censor these comments? This is a great recipe I just read, astounded at the comments.
She already deleted the best ones. All that’s left is the weak stuff, and for some reason, her attackers’ comments. 🤷♂️
It’s so disappointing! The HBH supporters have the most epic comebacks, and all that stays up are the hater attacks and a few soft cries for peace. (Mostly by the haters themselves who can’t even match wits, and thus need to surrender.)
I’m here for the brilliant rebuttals! I laughed so hard I cried reading how burnt the haters got.
Her team needs to vet the comments (all of them) before they ever get published. Not sure why they don’t. Most sites with this much traffic do that automatically.
This was amazing – keep those sandwich recipes coming! They may not be your favorite to post, but it’s nice to have something quick and easy to make on a weeknight. Keep up the great work. The spicy mayo was top notch!
Thanks so much Kari!! I love to hear that this sandwich turned out well for you, thanks so much for making it! xx
I’m confused. Do you lay both slices of bread on the tray, with only one layered with the ingredients? Then broil? Is the one plain slice of bread butter side down on the tray the one that goes on top?
I was wondering how the top slice gets browned? Just from lying on the tray?
It’s not that confusing. Try flipping it if you’re worried.
Hi Linda,
Since you are buttering the slices, they will brown with the oven being hot. You can view the photos above for reference, but cheese is going to melt on each side of the bread:) You really can’t mess this up, so however you build the sandwich will be just fine! I hope you love this recipe! xx
So so glad to see something besides bowls!!! I was getting bored with them but totally love this sandwich!!!
Hope you love the recipe, Nancy:)
Y’all are some crazy bitches.
Especially Denise. What a cow! 🙄
Cows are pretty nice animals. Let’s not insult them by comparing them to Denise.
Always nice to see a vegetarian option. But it’d be even nicer to see vegetarian recipes with protein!
Thanks for your feedback Cami! I hope you love the recipe:)
I made this today, minus spicy mayo, subbed pesto. It was heavenly!
Hey Lauretta,
Wonderful!! Thanks so much for making this recipe and sharing your comment, so glad to hear it was a winner! xT
This sounds wonderful! I will certainly try it. It reminds me of sandwiches I ate in the 70s with avocado, cream cheese and sprouts, but a 100 times better!
thank you for all your great recipes, you are always an inspiration!
and a very Happy 1st birthday to your Half Baked Harvest Every Day cookbook. 🙂
Thanks so much for your kind message Colleen!! Let me know if you give this sandwich a try, I hope it’s delish! xx
This looks amazing!
Thanks so much Jessica!!
I can’t wait to try this one out! It’s nice to find a vegetarian sandwich recipes that isn’t just hummus and standard veggies. One question that I have which is something I’ve been running into trouble with when I make sandwiches with avocados in them — is there a secret to stacking the avocadoes where they won’t just be pushed out the sides as soon as you squeeze down on the bread? I know this sounds silly, but I never have this problem with restaurant sandwiches and always have it with the sandwiches I make, so I must be doing something wrong!
I melted the cheese on the bread and did the tomatoes separate (roasted cut side up at 425 degrees F for about 15 minutes). After the cheesy bread was done I stuck the avocado slices directly on the melted cheese. If your avocados are room temp, there’ll be less of a chance for them to slide but this works even when they’re cold. Make sure the cheese is very well melted!
My sister and I love this blog and cook T’s recipes alllllll the time. I don’t think I’ve ever made anything that wasn’t 100% yummy and sooooo delicious, and that everyone who ate it didn’t do anything but love it. This sandwich was no exception. I used both pepperocini and pickles, and was lucky enough to find pea shoots at the grocery store! It also so happens that I had a loaf of homemade sourdough bread from yesterday and this was a really great way to highlight it. Thanks for such a wonderful recipe! Keep up the amazing work.
Hey Nicole,
Wonderful!! Thanks so much for making this recipe and sharing your comment, so glad to hear it was a winner! Thanks so much for your kind message! xT
Hey Melanie,
Thanks so much!! Maybe try slicing them thinner to see if that helps! I hope this turns out well for you! xT
I love avocados and this sandwich looks divine! Just bought avocados on sale!
Looking forward to making this sandwich! I have never committed before, and that’s a shame since I use your recipes time and time again. Last night I made your creamy wild rice soup with butter roasted mushrooms (again!), on our chilly March evening. It’s very sad to see a comment criticizing your verbiage, for goodness sake! With so many avenues to pursue online recipes, perhaps just moving on would be the best option for that commenter. Although that would be such a loss for her. Thank you for your delicious recipes, and for overlooking those that are unkind. Don’t change a thing!
Love to hear this Stephanie!! Let me know if you give this recipe a try, I hope you love it! xx
Thanks for a veggie sandwich! This sounds so good. Adding it to my list for lunch. 🙂 I’m always on the lookout for meatless options. Oh so good and yummy are fine by me! Keep surprising us with great meals!
Thanks so much Leslie!! I hope you love this recipe!! xx
Very good. I’m sorry to say this, but if there is any way you could stop saying “it’s SO good, you guys” or “so yummy!” I would be grateful! It’s annoying, like fingernails on a chalk board and makes me want to scream. Just saying I hope you enjoy it would go such a long way!
Really? So unnecessary.
As is this comment, I suppose 🙂
Shut up Denise. Seriously. The irony of you calling someone else annoying when you are just being a massive bitch is…astonishing.
Great recipe Tieghan. Don’t change a thing except for that pre-approval thing for your comment section. It’s needed.
Shut the hell up Denise. Get a damn life.
Love everything about you and your recipes Tieghan!
Definitely time to subject all comments to pre-approval. “Denise” and her ilk are like a bad case of pubic lice. Eradicate them.
Great recipe, keep up the great work, and please keep describing your craft however you like!
We’d all be grateful if you crawl back into the depths of the cesspool from whence you slithered, Denise.
Spotted the jealous person with no life! Not hard to trace where Denise came from. The t.r.o.l.l.s. are really running low on ammo these days. The only thing annoying around here is people like you, D.
I’d second Justina’s suggestion to you, Denise, but you seem to be more of a camel person.
She really should pre-approve the comments though. They will literally never stop polluting this place. They live for it, and have zero interests outside of that sad pursuit.
Let’s be fair though. They do have one additional interest: Blaming Creighton every time one of them gets shredded. If that’s really him though, he deserves the Pulitzer prize for his prolific literary skills.
The jealousy is so strong with that crowd. The exploding triggered behavior when it’s pointed out is so hilarious and predictable too. Gotta love the entertainment, and how easy they are to rile up.
I fully agree, Denise. Also curious what makes this sandwich “charming”? And a cookie recipe where the cookies were called “wholesome”. What?
Please, retire yummy and get a thesaurus.
Please stop creating fake accounts to agree with yourself, Denise. It just makes you look more foolish.
This is a place of joy. Quit being such a Denise Downer.
Thanks for trying the recipe Denise! Sorry you feel this way, but that’s just me:) xx
Tieghan, your recipes ARE yummy, (this sandwich included) and you rock! Keep up the great work.
I love to say it’s so good and super yummy all the time too!!🌟😊. Divine blessings to you, your page, and your yummy recipes ☺️🌷. Thank you bunches, Mirandalyn 🌷
Sounds like you get triggered very easily. Maybe you need therapy, meds or both?
Why would you even concern yourself with this, Denise? Seems rather petty.
Thanks for this great vegetarian sandwich, Tieghan! Not a huge onion fan, so I left those out, (kept the jalapeños!) but this was a great and easy weeknight dinner.
Why butter the outside of the bread if you aren’t grilling it?
Hi Emmie,
Since you are broiling it, the butter will give a nice golden crisp to the bread. Please let me know if you have any other questions! xT
This sounds amazing!
I know you said to not skip the smoked paprika but I really do not like anything smoked or chipotle flavored. Any other suggestions?
Hey Marla,
How about just plain paprika? That would work well for you! Let me know if you have any other questions, I hope you love this recipe! xx
