1. To a food processor, add the sliced pepperoni. Mix until most of the pepperoni is ground up, pulsing as you go. Add the ground beef and sausage. Form meat into 4 patties. 2. To a large skillet over medium/med-high heat, melt the butter and olive oil until butter is melted. If using mushrooms, saute them until done, 1-2 minutes. Remove with slotted spoon and set aside. 3. Add the patties to the pan and cook 4-5 minutes per side until cooked thru. Pat the burgers down with the spatula as needed to retain a wide burger (enough to cover the bun). 4. When burgers are just about done, place mushrooms on burgers (if using), then 1 slice each of the cheeses on top of each burger. Reduce heat to low (or turn burner off if electric oven), cover tightly and let steam until cheese is melted (1-2 minutes). 5. Place burgers on top of bottom bun then spread warmed pizza sauce over top of melted cheese. Close up buns and enjoy. ---------------------------------------------------------------------------
