1 (26 oz.) bag of frozen meatballs
1 (8 oz.) bag of shredded mozzarella
1 (24oz.) jar of spaghetti sauce
1 pack sub rolls
1. Turn the crock pot on high. Pour 1/3 of the jar of sauce into the bottom of the crock pot. Add the entire bag of frozen meatballs then pour the rest of the sauce over the meatballs.
2. Put the lid on the crock pot and cook for about 3 hours, occasionally stirring the meatballs.
3. Cook meatballs until cook through, about 3 hours. Once the meatballs are cooked slice the block of cheese and lay the slices over the top of the meatballs. If using shredded cheese sprinkle the cheese over the top of the meatballs. Replace the lid.
4. Continue to cook the meatballs until the cheese has melted.
5. Serve on sub rolls.
