This Northeastern standard is thought to have originated in the Philadelphia area. Stromboli is a flavorful twist on a traditional sandwich. It's similar to a calzone -- a pizza crust folded in half and stuffed with meats, cheeses or vegetables. Stromboli is rolled into a log shape, and it's just as easy to make as it is tasty. Simply unroll a premade pizza crust and stuff it with ham, pepperoni and mozzarella cheese. Roll up the sides and pinch together, forming a middle seam before cooking. Feel free to experiment with your favorite spices and mustards to give your palate a little kick.
