Pizzetta is a small pizza that is perfect for a single serving or a light meal. It typically has a thin crust and is topped with a variety of ingredients, such as tomato sauce, cheese, vegetables, and meats. Pizzetta can be served as an appetizer or as a main course, and is often enjoyed in Italian restaurants or at home. It's a great option for those who want the flavors of pizza without the size and heaviness of a traditional pie.
