My calzone, turned into a stromboli and was a really big hit here at our house. This could be because I haven't made anything over the last week. I browned ground beef, combined it with cottage cheese, cheddar, and spices for the filling. I rolled out the pizza dough to a rectangle then lengthwise stuffed the center with the meat mixture. I cut strips on the sides, and folded them over each other....it made it looked like I actually braided it :) I used an egg wash over the entire roll, sprinkled it with sesame seeds, then baked it in a 425 preheated oven for about 25-30 minutes.
This is really a super versatile idea. Ham and cheese, pepperoni and marinara, etc., etc., etc. I can stuff just about anything in this dough!
