Pepperoni and cheese calzone is a delicious and filling meal that is perfect for a cozy night in. To make this calzone, you will need pizza dough, pizza sauce, shredded mozzarella cheese, and pepperoni slices. Preheat your oven to 425 degrees F. Roll out the pizza dough into a circle shape. Spread the pizza sauce over half of the dough, leaving a small border around the edges. Sprinkle the shredded mozzarella cheese over the sauce, and then add a generous amount of pepperoni slices. Fold the other half of the dough over the filling and crimp the edges to seal. Cut a few slits in the top of the calzone to allow steam to escape. Place the calzone on a baking sheet and bake in the preheated oven for 20-25 minutes, or until the crust is golden brown and the cheese is melted and bubbly. Serve hot and enjoy!
