Meatball Subs (Crock Pot and Oven)

Our family picked up a super yummy meatball sub from Costco and I thought, "I can make that!" So here is my version. Enjoy!

Meatball Subs (Crock Pot and Oven)

Ingredients:

• small loaf of French bread or desired buns
• garlic butter
• 1 pkg frozen meatballs
• 2 jars spaghetti sauce
• 1 pkg. provolone cheese slices
• Parmesan cheese, grated

Directions: 

1. Spray your Crock Pot with non-stick spray and add your meatballs and ONE jar of the spaghetti sauce. Cook until meatballs are heated all the way through (a couple hours on high, or a little longer on low... probably doesn't really need to cook all day, as the meatballs are precooked).
2. Near the time you want to eat, pour your second jar of spaghetti sauce in a sauce pan to heat through. Serve each person a portion of the sauce in a small bowl for dipping.
3. Split your French bread loaf or other desired buns and spread the cut-side with garlic butter. Place on a foil/non-stick mat lined baking sheet and place under the broiler in your oven to toast. 
4. Once toasted, remove from the oven. 
5. Change the oven from broil to bake at 350. 
6. Assemble your sandwich by putting first a layer of provolone, then your meatballs with some of the sauce they cooked in, then a sprinkling of Parmesan, then a final layer of provolone. Top with the top portion of the bread. 
7. Cover the tray tightly with foil and place back in the oven until the cheese is melted, just a couple of minutes.
