Meatball Sub

Ingredients

• 1 lb ground beef
• ½ cup Italian breadcrumbs
• 1 egg
• ¼ cup Parmesan cheese, grated
• 1 tsp garlic powder
• ½ tsp onion powder
• ½ tsp dried oregano
• ½ tsp salt
• ¼ tsp black pepper
• 1 tbsp olive oil
• 24 oz marinara sauce
• 4 hoagie rolls
• 8 provolone cheese slices
• 2 tbsp fresh parsley, chopped (optional)

Steps

1. Preheat oven to 375°F (190°C). In a large bowl, combine ground beef, breadcrumbs, egg, grated Parmesan, garlic powder, onion powder, oregano, salt, and pepper. Mix until just combined, then form into 1-inch meatballs (about 16-20 meatballs).
2. Heat olive oil in a large skillet or Dutch oven over medium-high heat. Brown the meatballs on all sides, working in batches if necessary, until a crust forms. They don't need to be cooked through.
3. Pour the marinara sauce over the browned meatballs. Bring to a simmer, then reduce heat to low, cover, and cook for 15-20 minutes, or until meatballs are cooked through and tender.
4. While meatballs simmer, slice hoagie rolls lengthwise, being careful not to cut all the way through. Place rolls on a baking sheet and toast in the preheated oven for 3-5 minutes, or until lightly golden.
5. Spoon several meatballs and plenty of sauce into each toasted hoagie roll. Top each with 2 slices of provolone cheese.
6. Return the subs to the oven or place under a broiler for 2-4 minutes, until the cheese is melted and bubbly.
7. Garnish with fresh chopped parsley, if desired, and serve immediately.
