What Do You Put on Meatball Subs?

The best part about making your own meatball subs at home is that you can customize your sandwiches with your favorite toppings. As you’re preparing your own subs, try these topping ideas:

  • Cheese. In addition to mozzarella cheese, you can also top your sandwich with provolone or parmesan for even more Italian flavor.
  • Vegetables. Add some veggies to your meatball subs for added crunch. Top your subs with sliced bell peppers, onions, or mushrooms. Or add some pickled veggies, like pepperoncini or banana peppers, for some added spice.
  • Herbs. Give your sandwiches some fresh flavor with the help of fresh herbs. Try topping your meatballs with fresh basil, parsley, or oregano.
