These bite-sized appetizers are perfect for any party or gathering. To make these pinwheels, you'll need puff pastry, pizza sauce, shredded mozzarella cheese, and sliced pepperoni. First, preheat your oven to 400°F. Roll out the puff pastry and spread pizza sauce over the top. Sprinkle shredded cheese and sliced pepperoni over the sauce. Roll up the pastry tightly, then slice into 1-inch pieces. Place the pinwheels on a baking sheet and bake for 15-20 minutes, or until the pastry is golden brown and puffed up. Serve hot with additional pizza sauce for dipping.
