Preheat Oven to 375 degrees. Cook pasta accordingly, drain. Put pasta back in pot, add sauce, DICED pepperonis and 1 1/2 cups cheese. Stir together. Pour into large baking/casserole dish. Top with remaining cheese and SLICED pepperonis (enough to cover the top!) Bake for 20 Minutes! ENJOY! Your kids will LOVE it, and it makes for GREAT leftovers for lunch the next day!
