Preparation -
Coarsely chop the pepperoni. In a mixing bowl, combine the chopped pepperoni with the ground beef, bread crumbs, and pizza sauce. Shape the mixture into 4 burger patties. Grill or broil for 5 to 6 minutes per side or until nicely browned on the outside with no trace of red on thie inside. Place one slice of Mozzarella on each burger. Grill for about one more minute to melt the cheese. Serve with extra pizza sauce on the side - to use instead of ketchup.
