Preheat the oven to 400℉, and oil the baking sheet. Place the tortillas on the baking sheet, and slide them over the greased surface so that the bottom side is lightly coated with oil.
Sprinkle 3 tablespoons of the cheese over each tortilla, and divide the pepperoni between tortillas. Top each with 3 more tablespoons cheese.
Bake for 5 minutes. Remove the baking sheet from the oven, and carefully fold each tortilla in half. Bake an additional 5 minutes or until browned and crisp. If after 5 minutes they are not quite finished, flip the tortillas and bake for a few minutes more.
Cut each tortilla into two or three wedges or serve whole. They are delicious as is or with a side of marinara for dipping.
