2 quarts water
1 lb meaty ham bone or ham chunks
1 celery stalk with leaves, finely chopped
1 large carrot, finely chopped
1 medium onion, finely chopped
1 bay leaf
Drain the soaked beans, rinse and place in crockpot or slow cooker. Add the remaining ingredients and cover the cooker.
Cook soup on high 5 to 6 hours; lower temperature, remove bay leaf and soup is ready to serve.
NOTE: Personally, I like to add some salt and freshly ground black pepper.
