Stromboli are a type of baked bread filled with various Italian cheeses (typically mozzarella) and Italian cold cuts (typically salami, capocollo, and bresaola) or vegetables, and marinara sauce, served hot. The dough is either Italian bread dough or pizza dough. Stromboli are an Italian-American dish invented in Philadelphia by the mid-20th century.[1] The dish is ultimately named for the volcanic island off the coast of Sicily, by way of the 1950 Roberto Rossellini film of the same name.
Stromboli are similar to a calzone or scaccia, and the dishes are sometimes confused.[2] Unlike calzones, which are always stuffed and folded into a crescent shape, stromboli are typically rolled or folded into a cylinder, and may sometimes contain a thin layer of tomato sauce on the inside.[3]
