In a bowl combine the quinoa, sunflower seeds, mashed cannellini beans, bread crumbs, egg, garlic, chipotle chile powder, salt and pepper. Mix well to moisten the ingredients and then form into 4 or 5 equal burger patties (I made 5). Place on a plate and put in the fridge.
Preheat the oven to 375 degrees F.
Slice the sweet potatoes into 1/8 inch thick straws or use a mandolin slicer and do the same. Place the straws on a baking sheet and toss them with the melted coconut oil, curry powder, salt and pepper - toss well. Divide the straws between two baking sheets. Bake for 15 minutes, toss, and then bake another 15-20 minutes more or until the edges just begin to crisp.
To make the tahini sauce, add the tahini, curry paste, maple syrup, lemon juice and soy sauce to a bowl. Add a few tablespoons of water and mix until smooth and combined, if needed, add more water to thin. Top with sesame seeds.
Heat the olive oil in a large skillet over medium heat. Grab the burgers and cook until golden and crisp, about five minutes per side.
Once the burgers are finished, remove and place on plate. Next add a drizzle more of olive oil to the skillet and once hot, add the Halloumi slices. Cook for 1-2 minutes per side or until lightly golden. Remove and drain on paper towels.
Spread the bottom of each bun with the tahini sauce, top with a burger and fried Halloumi and crispy sweet potatoes. Add the top bun. Serve with more tahini sauce. Enjoy!!
