Stromboli is a Philadelphia favorite that is similar to a calzone. It’s essentially pizza toppings baked inside a pizza dough pocket. This version is made the easy way by using frozen bread dough instead of making pizza dough from scratch. You can easily alter the filling ingredients to suit your tastes. These sandwiches also freeze great. Simply bake them for 30 minutes instead of an hour, then freeze. When ready to bake them simply remove from the freezer and bake for 30 minutes at 350 degrees F.
