A calzone is a type of Italian pastry that resembles a folded pizza. It is made from pizza dough and typically filled with ingredients such as cheese, meats, and vegetables. The filling is enclosed within the dough, which is then baked until golden brown. Calzones are often served with a side of marinara sauce for dipping. They originated in Naples, Italy, and have become popular in various regions, especially in the United States. Similar to pizza, calzones can be customized with a variety of fillings to suit different tastes.
