Calzone
From WOI Encyclopedia Italia
A calzone, sometimes referred to as a stuffed pizza, is an Italian turnover made of pizza dough and stuffed with mozzarella cheese, and sometimes also ricotta cheese, or even monterey jack cheese, meat, vegetables, etc. The dough is folded over, sealed along one edge and baked in an oven and often served with marinara sauce (a sauce similar to tomato sauce). Roughly sandwich-sized calzones are often sold at Italian lunch counters or by street vendors because they are easy to eat standing up or while walking.
Sweet versions, usually smaller, cookie-sized, are a specialty in the Marche.
Calzones are similar to stromboli, but traditionally the two are distinct dishes.
Calzones are a relative specialty in most Western countries, often being served as a complement to pizza, a similar but much more common dish.
This dish causes some amusing confusion for Central and South Americans where calzones are girls' underpants, in written slang.
