So what's the difference?
A free peanut butter pie lol
Nah, seriously. Calzone is just folded over and uses ricotta, stromboli is rolled and uses mozzarella. Calzone has sauce, stromboli no sauce baked in, but they give you(for a large) 3 big dipping sauce containers. Picture a half moon, a calzone. Big ass horseshoe, stromboli.
When I lived up northern PA both were folded over, so maybe its regional thing?
