Ready-made pie dough is used to make these quick, easy panzerotti, which are filled with a hefty mix of deli meats and cheeses, such as garlicky mortadella, salami, ham and Asiago. Sun-dried tomatoes and olives offset the richness of the other fillings, though you can add whatever ingredients you like, be it browned Italian sausage and eggplant or fresh mozzarella, tomato sauce and basil. Brush them with beaten egg yolk before baking them until golden brown.
