Mini Meatball Subs

Step 1

Preheat an oven to 350 degrees F (175 degrees C).

Step 2

Combine ground beef, onion, green pepper, crackers, and egg in a large bowl. Season with Worcestershire sauce, garlic, seasoned salt, and pepper; mix well. Form mixture into 8 meatballs. Place meatballs in a 9x13 inch baking dish.

Step 3

Bake meatballs in the preheated oven for 20 minutes. Pour the spaghetti sauce into a large saucepan; bring to a simmer over low heat. Stir baked meatballs into the simmering sauce. Do not turn oven off. Simmer sauce until meatballs are fully cooked, about 20 minutes.

Step 4

Place one meatball, a sprinkle of mozzarella, a sprinkle of Parmesan, and a bit of sauce between each roll. Place sandwiches in hot oven; bake until cheeses melt, about 7 minutes.
