In a small bowl, combine sour cream, garlic, salt, and pepper. Lay pitas flat on two cookie sheets. Spread a liberal amount of sour cream sauce on top of each pita. Evenly spread meat, olives, onion, and banana peppers and feta on top.
Place in oven at 425 F for 7 to 12 minutes, until pita is toasted and cheese is lightly browned on top. Cut each pita into 4 triangles and top with tomatoes and cucumbers.
This recipe is great for families — each individual can choose their own toppings. Pitas can be used to make Italian pita pizzas, Mexican pita pizzas, and Reuben pita pizzas.
