- 1 (20 oz) bag frozen meatballs (regular or Italian style)
- 1 tablespoon Italian seasoning
- 1 (24 oz) jar spaghetti sauce
- 1 cup softened butter
- 1 teaspoon garlic powder
- 1 teaspoon Italian seasoning
- 2 loaves Italian or baguette bread
- 1 cup shredded mozzarella cheese
Place meatballs, 1 tablespoon Italian seasoning and spaghetti sauce in the slow cooker. Cook on low for 8 hours.
About 30 minutes before serving, combine butter, garlic powder, and 1 teaspoon Italian seasoning. Slice loaves of bread lengthwise and spread garlic butter on the inside of each loaf.
Put loaves back together and cut each loaf into thirds crosswise to create 6 sandwiches.
Place garlic bread cut side up on a baking sheet. Heat under the broiler until toasted.
Top toasted bread with meatballs, sauce, and a sprinkle of mozzarella cheese for a hot and melty meatball sub.
For a freezer meal, place meatballs, Italian seasoning, and spaghetti sauce in a gallon-sized freezer bag. Place mozzarella cheese in a sandwich freezer bag. Lay both flat to freeze. Freeze the 6 garlic bread sandwiches in two gallon-sized freezer bags. To serve, thaw ingredients and follow cooking directions in the recipe.
