What is "stromboli"?

Stromboli is a type of Italian-American turnover that is made by folding a pizza dough around a variety of ingredients, typically including cheese, meats, and vegetables. The dough is then baked until it is crispy and golden brown on the outside and the filling is hot and melted on the inside. Stromboli is similar to a calzone, but is typically rolled into a cylinder shape instead of being folded over. The filling for stromboli can vary widely, but often includes mozzarella cheese, cured meats such as pepperoni or salami, and vegetables such as peppers and onions. Stromboli is often served as a handheld meal or snack, and is popular in many parts of the United States, particularly in the Northeast.
