Instructions

Making this recipe is an incredibly easy affair. It only takes a few steps and a few minutes.

Step 1: Cook the Noodles and Make the Meatballs

Cook the noodles according to the package directions for al dente, then drain them and dump them into a large bowl. Prepare the meatballs according to the package directions and set them aside.

Step 2: Add the Sauce

Add the spaghetti sauce to the cooked spaghetti and meatballs. Toss with tongs until fully coated.

Step 3: Toast the Buns, If Desired

Split the buns in half and cover with garlic butter.

Add ¼ cup of mozzarella cheese to each side or more. Place them on a rimmed baking sheet.

Place them under a preheated broiler until the cheese is melted with a few golden spots. Remove them from the oven and place them on a plate.

Step 4: Make the Subs

Using tongs, transfer ¼ of the spaghetti onto each sub and add 4 meatballs. Sprinkle with mozzarella or parmesan cheese.

Broil until cheese is melted. Serve immediately.

Hint: Keep a close eye on your subs when toasting them so they don't burn.
