Chili meatball subs are a delicious twist on the classic meatball sub. These subs are packed with flavor, combining juicy meatballs with a spicy chili sauce. The meatballs are made with a mixture of ground beef, breadcrumbs, and spices, and are cooked until tender and flavorful. The chili sauce is made with tomatoes, onions, garlic, and a blend of spices, creating a rich and hearty sauce. The meatballs and chili sauce are then layered onto a sub roll and topped with melted cheese for a satisfying and comforting meal.
