Classic Meatball Sub

Preheat your oven to 350°F (177°C). Place the meatballs in the microwave and partially thaw them for 30 seconds.

Take a large pot and combine the partially - thawed meatballs with the spaghetti sauce. Turn the heat to medium and cook the mixture for 10 - 12 minutes, or until the meatballs are heated through.

Once the meatballs are heated through, use a spoon to transfer the meatballs onto the bottom half of the submarine roll. Sprinkle parmesan cheese over the meatballs. Then, cover the meatballs with the top half of the roll.

Place the prepared sub on a foil - lined baking sheet. Put the baking sheet in the preheated 350°F (177°C) oven and bake for 5 minutes.
