In a dutch oven, brown beef in oil on both sides. Add onion and celery when meat is almost browned. Add broth; cover and simmer 3-4 hours or until meat is tender. Remove meat; cool and shred. Drain vegetables, reserving 1-1/2 cups broth. Skim off any fat. Return the meat, vegetables and broth to dutch oven; add the remaining ingredients. Simmer until heated through. (Keeps well in a slow cooker on Low heat.) Remove bay leaf before serving.
