Vegetable Soup

In crock pot I cook on low soup bone, roast, onion, celery, water and soup base overnight or until meat is fork tender. I remove meat and bone and then cool broth until fat rises and congeals and can be removed from broth. Cut meat into small pieces, removing any fat you find, and add back to broth. Cook potatoes and veggies, drain each and add to soup along with tomato sauce and a cup or 2 of water. Simmer in crock pot a couple of hours.
