Italian Meatball Subs. Homemade beef parmesan meatballs in a fresh marinara sauce topped with melted mozzarella cheese all on toasted bread. The best meatball sub recipe!
Start with high-quality ground beef (preferably 80/20 which gives the right amount of fat for a juicy meatball). If you use 85/15, it will be a tad less juicy meatball). Mix ground beef, salt, pepper, garlic powder, panko bread crumbs, fresh parsley, egg, and parmesan cheese in a bowl. I like to use my hands to get it really incorporated together.
