This recipe can be made on the stove, as well. Brown the beef and add the remaining ingredients EXCEPT for the elbow noodles. Let the soup simmer on the stove for 1-3 hours, until the beef is nice and tender and falls apart. During the last ten minutes of cooking, add the elbow noodles to the pot and cook until tender.
