2lb. 13oz. of your favorite pasta or spaghetti sauce
1 - 38oz. bag frozen Italian meatballs (fully cooked)
shredded mozzarella cheese
1 chopped onion
1 chopped green pepper
long steak sandwich rolls
Thaw the meatballs--drain. Add meatballs, sauce, chopped onion and
chopped green pepper to a large crockpot--stir. Cook on low until well
heated--test a meatball by slicing it in half to make sure it has warmed all the
way through. Once hot, put 4-5 meatballs in each steak roll. Add a little
sauce and some onions/peppers from the sauce to the top of the meatballs
and sprinkle each sandwich with mozzarella cheese. You can make this
recipe without thawing the meatballs but cooking time will be a few hours
