Preheat the oven. Set it to 425°F (220°C). For extra crisp pitas, preheat a sheet pan inside the oven.
Prep the base. Stir 1 tablespoon olive oil with 1 small grated garlic clove, 1/2 cup tomato sauce, and a pinch of oregano, salt, and pepper.
This is your quick sauce.
Toast the pitas (optional, for crunch). Place pitas on the hot sheet for 2–3 minutes per side to firm them up.
Sauce the pitas. Spread a thin layer of the seasoned tomato sauce over each pita. Don’t oversauce—leave a small border.
Add cheese and toppings. Sprinkle a light layer of mozzarella (if using), then add spinach, tomatoes, red onion, chickpeas, and olives. Finish with crumbled feta.
Season and drizzle. Add a pinch of oregano and red pepper flakes.
Drizzle with a little olive oil for golden edges.
Bake. Return to the oven for 8–10 minutes, until the cheese melts and the pitas are crisp and lightly browned.
Finish fresh. Top with chopped basil or parsley and a quick zest or squeeze of lemon for brightness. Slice and serve hot.
