1. Add the meat, shallot, oregano, paprika, chili flakes, and a pinch of salt, and pepper to a bowl. Mix until combined. Coat your hands with a bit of oil and roll the meat into rounded tablespoon-size balls (will make 16-18 meatballs). Set aside. 2. In a bowl, toss the zucchini and peppers with 1 tablespoon olive oil, salt, and pepper. Preheat the grill or grill pan to high. 3. Meanwhile, make the vinaigrette. Combine all ingredients in a glass jar and whisk until smooth. Taste and adjust the salt and pepper.5. Grill the peppers and zucchini until softened, 3-4 minutes per side. Remove from the grill to a serving plate and toss with half the vinaigrette.6. Heat a large skillet over medium-high heat and add 2 tablespoons of oil. Add the meatballs and sear until crisp and cooked through, about 8-10 minutes, turning them 2-3 times. Transfer to a plate.7. Serve the meatballs warm, tossed with the vegetables. Add a large dollop of tzatziki to each plate, then crumble the feta over top. Enjoy with naan and/or french fries.
