This tasty calzone recipe is perfect for a lunch or dinner. To make the calzone, you will need 1 pound of pizza dough, 1/2 cup of tomato sauce, 1/2 cup of shredded mozzarella cheese, 1/2 cup of sliced pepperoni, and 1 beaten egg. Preheat the oven to 400°F. Roll out the pizza dough into a circle. Spread the tomato sauce over half of the dough, leaving a 1-inch border around the edges. Sprinkle the shredded mozzarella cheese and sliced pepperoni over the tomato sauce. Fold the other half of the dough over the filling and pinch the edges to seal. Brush the beaten egg over the top of the calzone. Bake for 20-25 minutes until the crust is golden brown. Let the calzone cool for a few minutes before slicing and serving. Enjoy!
