Pepperoni and cheese roll-ups are a fun and easy snack that is perfect for parties or after-school snacks. To make this dish, you will need the following ingredients: pizza dough, tomato sauce, shredded mozzarella cheese, sliced pepperoni, and any other toppings you desire. Begin by preheating your oven to 425 degrees Fahrenheit. Roll out your pizza dough on a floured surface and cut it into strips. Spread tomato sauce over each strip, leaving a small border around the edges. Sprinkle shredded mozzarella cheese over the sauce, followed by the sliced pepperoni and any other toppings you desire. Roll up each strip tightly and place them on a baking sheet. Bake the roll-ups in the preheated oven for 12-15 minutes, or until the crust is golden brown and the cheese is melted and bubbly. Serve hot and enjoy!
