This delicious stromboli recipe is perfect for a party or game day. To make the stromboli, 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 rectangle. Spread the tomato sauce over the dough, leaving a 1-inch border around the edges. Sprinkle the shredded mozzarella cheese and sliced pepperoni over the tomato sauce. Roll up the dough tightly, starting from the long side. Pinch the edges to seal. Brush the beaten egg over the top of the stromboli. Bake for 20-25 minutes until the crust is golden brown. Let the stromboli cool for a few minutes before slicing and serving. Enjoy!
