Open-Faced Meatball Sub Casserole

If you have a taste for a meatball sub sandwich, make it at home! Open-Faced Meatball Sub Casserole takes the same tasty ingredients that are in a traditional meatball sub, and turns them into an open-faced casserole. If you have meatballs leftover from the spaghetti and meatballs you made last night, use them in this casserole for either lunch or dinner. It's a fun dish that's easy to make and tastes delicious.
