While the oven is preheating - heat a skillet over medium heat. Add 1 teaspoon of oil - Add onions, green peppers cook for 5 minutes. Add garlic cook for an additional 2 minutes. Add Beef.
Brown beef and drain excess fat
Add in pizza sauce, milk, pepperoni, pinch of salt and pepper and noodles
Gently mix everything together
Place in a 2 quart casserole dish -- I would grease the dish with a little oil.
Top with cheese - bake for 30 minutes -- for the last 5 minutes put the broiler on to brown the top
Enjoy!!! This is a great meal to freeze and reheat
