For a twist on the classic meatball subs, try making them with chicken Parmesan meatballs. In a Thermomix, combine ground chicken, breadcrumbs, grated Parmesan cheese, minced garlic, and a variety of Italian herbs and spices. Shape the mixture into meatballs and bake them in the oven until cooked through. To assemble the subs, use Italian sub rolls, marinara sauce, and slices of mozzarella cheese. Spread marinara sauce onto the rolls, add the chicken Parmesan meatballs, and top with mozzarella cheese. Place the subs under the broiler until the cheese is melted and bubbly. These chicken Parmesan meatball subs are a delicious twist on a classic favorite.
