Savory meatballs nestled in a warm sub roll, topped with marinara sauce and melted cheese. This hearty sandwich is a true comfort food that will satisfy any cravings!
Preheat your oven to 375°F (190°C).
In a large bowl, combine ground beef, breadcrumbs, grated parmesan cheese, minced garlic, beaten egg, chopped parsley, salt, and pepper. Mix until well combined.
Form the mixture into meatballs about 1 inch in diameter.
Place meatballs on a baking sheet lined with parchment paper and bake for 20 minutes or until cooked through.
While the meatballs are cooking, heat the marinara sauce in a saucepan over medium heat.
Once the meatballs are done, transfer them to the saucepan with the marinara sauce and simmer for 5 minutes.
Cut the sub rolls in half lengthwise and place them on a baking dish.
Spoon the meatballs with marinara sauce into each sub roll, ensuring they’re generously filled.
Top each loaded sub with mozzarella cheese.
Bake the assembled subs in the oven for an additional 10 minutes, or until the cheese is melted and bubbly.
Remove from oven, let cool for a minute, then serve warm.
