my adopted italian grandfather used to call me stromboli. it's italian american slang for all twisted up (in the head).
so, a stromboli is pizza dough rolled out to large squarish shape, then spread with ingredients (as varied as any pizza topping) then rolled up like a jelly roll forming a loaf, as moose said. it's then baked until golden and the dough is cooked through.
btw, nice job moose! that looks delicious.
a calzone is a round pizza dough where half is spread with pizza like ingredients (the classic being ricotta, mozzarella, and ham), then it's folded over to form a half moon. the edges are crimped and it's either deep fried or baked.
both are optionally served with a side of sauce for dipping.
