Cut rolls in half. Press half into 3 inch circles. Set remaining halves aside. Place the 3 inch circles you have pressed out into the bottom of a sprayed 9x13 inch baking dish in 4 rows of 6. Press to make sure the bottom of pan is completely covered.
Combine pizza sauce and frozen meatballs and microwave about 8 minutes until sauce is bubbling and meatballs are thawed through. Add chopped pepperoni and mix well. Pour mixture evenly over dough pieces in pan. Sprinkle with Parmesan cheese.
Place the remaining dough halves on top of the mixture in 4 rows of 6. Cover with sprayed plastic wrap and let rise until dough doubles on top. Remove plastic and bake at 350°F 12-18 minutes. Cover with foil if needed to prevent over browning but make sure dough is baked through. Remove from oven and sprinkle with cheese blend. Bake an additional 5 minutes or until cheese is nicely melted.
