1/2 cup pizza sauce
4 (7- or 8-inch) flour tortillas
4 ounces (1 cup) shredded mozzarella cheese
1/2 (3.5 ounce) package pepperoni slices

Preheat oven to 350 degrees F.

Spread pizza sauce evenly over tortillas to within 1 inch of edges. Sprinkle each evenly with cheese. Arrange 1/4 of pepperoni slices down center of each tortilla. Roll up each tortilla; wrap each in foil. Bake for 10 to 15 minutes or until thoroughly heated and cheese is melted.
