- Preheat your oven to 400°F (200°C).
- In a large mixing bowl, combine the ground beef, breadcrumbs, grated Parmesan cheese, egg, minced garlic, dried oregano, dried basil, salt, and pepper. Mix until well combined.
- Shape the meat mixture into meatballs, about 1 to 1.5 inches in diameter.
- Heat a drizzle of olive oil in a large skillet over medium heat. Once hot, add the meatballs in batches and cook until browned on all sides, about 6-8 minutes. Transfer the browned meatballs to a baking sheet.
- Bake the meatballs in the preheated oven for 10-12 minutes, or until cooked through.
- While the meatballs are baking, prepare your sandwiches. Split the hoagie rolls or sandwich buns and place them on a baking sheet.
- Spread marinara sauce on one side of each roll. Place a few meatballs on top of the sauce, then add a spoonful of additional marinara sauce over the meatballs.
- Top the meatballs with sliced mozzarella cheese.
- Optional: Add sliced onions, bell peppers, or mushrooms on top of the cheese.
- Place the baking sheet in the oven and bake for 5-7 minutes, or until the cheese is melted and bubbly, and the rolls are lightly toasted.
- Remove the sandwiches from the oven and serve hot.
