Put the 3 cups water, bouillon cubes, salt and mashed tomatoes in crock pot. Turn the crock pot on so the cubes will begin to dissolve.

Meanwhile, cut up vegies. Put meat into the pot with vegies on top. Frozen package of vegies goes in during last half of cooking time. Stir couple times during cooking time. Cook 12 hours on low (4 hours on high).

When the soup is done, remove shank from pot. Remove meat from bone, cutting it into small pieces and return to pot. Stir meat into soup and serve.
