1. Meatballs: Mix meats, garlic, parsley, Parmesan, breadcrumbs, eggs, salt, and pepper. Form into balls and bake at 375°F for 25-30 minutes.
2. Assembly: Spoon marinara sauce on the bottom of each toasted roll, add meatballs, top with more sauce, and cheese slices. Broil until cheese is melted and bubbly.
3. Serve: Enjoy hot with extra marinara sauce and a sprinkle of fresh parsley.

Tips:

• Bake meatballs instead of frying to reduce oiliness and ensure even cooking.
• Toast the hoagie rolls lightly to keep them from getting soggy.
