How to Make It
Preheat oven to 450°.
Crush tomatoes with garlic and black pepper in a small bowl.
Arrange 4 pitas on a large rimmed baking sheet; brush both sides of pita with oil. Top pitas with equal amounts of the tomato mixture, feta, olives, and bell peppers.
Bake 7-8 minutes or until edges are golden.
Remove pitas from oven; top each with 1/4 cup arugula.
Drizzle with additional oil, if desired. Serve.
