Ingredients

10 ounces Italian style frozen meatballs, thawed
1 cup marinara sauce, plus extra for dipping
½ cup grated provolone or mozzarella cheese
2 tablespoons Parmesan cheese
4 hoagie rolls, split
Optional garnish: chopped fresh herbs such as parsley, basil, or oregano

Instructions

Preheat the oven to 425°F. While the oven heats, allow the thawed meatballs to sit on the counter and come to room temperature. Place the open hoagie rolls on a large rimmed baking sheet. Toast the rolls in the preheated oven until lightly browned, about 2 to 3 minutes. Meanwhile, in a large bowl, toss together the meatballs and marinara sauce. If the meatballs are very large or still really cold, you'll want to warm them up before adding them to the rolls. To do so, you can warm them in a saucepan with the marinara on the stovetop over low heat, or place them in a microwave-safe bowl with the sauce and warm in the microwave.
Place the meatballs and sauce on the bottom half of each hoagie roll. Top with cheese.
Bake the subs, uncovered, until the meatballs are heated through and the cheese is melted, about 3 to 5 minutes. If you'd like the cheese more browned on top and the rolls toastier, place the subs under the broiler for a minute or so at the very end. Just keep a close eye on them because they can burn quickly. Close the subs and serve with additional marinara sauce for dipping.

Notes

CROCK POT METHOD:

Place a bag of meatballs and 1 jar of marinara sauce in a slow cooker. If you're using a Crock Pot, there's no need to thaw the frozen meatballs before you dump them into the pot. Cook the meatballs in the sauce on LOW for 3-4 hours, or until the meatballs are heated through. Assemble and bake the meatball subs according to the recipe instructions above.

You can adjust the ingredients to prepare just one sub (or more) at a time. The cooking instructions remain the same.
