Meatballs are not just italian The spanish have a big variety of meatball dishes, too. One thing that they all have in common is that they each have a wonderful sauce, like this one. Fresh mint is a wonderful flavor to complement the lamb. These simple lamb meatballs are made with just breadcrumbs and egg and flavored with finely chopped mint leaves. The meatballs are then fried in olive oil. Next, a tomato sauce is made with onion, garlic, wine, and beef broth to make the sauce flavorful and rich. Meatballs are simmered in the sauce and served warm with baguette slices to soak up the tomato sauce.
