1 can (8 ounces) crescent roll dough
1/2 cup finely chopped pepperoni, about 2 ounces
1 cup shredded Mozzarella cheese
2 to 3 tablespoons finely chopped mushrooms or finely chopped bell pepper
1 tablespoon finely chopped onion
1 cup marinara or pizza sauce, for dipping
Roll a rectangle up tightly, starting with short end. Slice into 5 to 6 even slices and place on the baking sheet, leaving a few inches between them. Repeat with the remaining rolls.
Bake for about 14 to 18 minutes, until nicely browned. Serve with warmed marinara or pizza sauce.
