Homemade Meatball Subs

"Homemade Meatball Subs are one of the best classic sandwiches that you can make at home. The best homemade meatballs smothered in homemade marinara sauce, topped with copious amounts of mozzarella cheese, and then popped under the broiler to melt everything. I have even used this same meatball and sauce and used to top pasta, to all of the fanfare. Homemade meatballs taste so much better than pre-made ones you can buy at a store, and they are really easy to make. A lot of people get intimidated by the thought of rolling them, but this is a no-fail recipe that is tried and true. I have used this same recipe for my homemade meatball subs for years, and they turn out great every single time. "
