The original recipe call for ground veal and ground sirloin. I omitted the veal and substituted hamburger for the veal. In heavy, large wide pot heat oil over medium-high heat. Add veal, sausage, and beef to pot and cook, breaking up meat into with spoon, until well browned, about 5 to 10 minutes. Using slotted spoon, transfering meat to large bowl (some bits of meat may remain in pot). Add onions and garlic to pot and cook until tender, about 8 minutes. Return meat to pot. Add wine and bring to a simmer. Stir in tomatoes with their juices, broth, bay leaves, and oregano. Cover and cook over medium-low heat until the meat is very tender, stirring occasionally, about 1 hour. Uncover and simmer over medium heat until sauce thickens slightly, about 1 hour longer. Season with salt and pepper as desired.
