Ham bone  and fat from cooked ham- 1
Left over ham - diced - 2 cups
Navy beans or northern beans - 2 pounds

Boil clean ham bone and fat for four hours.  Remove bones and fat - save broth.
 Prepare dried beans according to package to cooking stage.  Add beans and chopped onion to ham broth.  Cook for two hours - until beans are desired consistency.    

Fry or broil bacon.  Chop.
