Ham Bone Soup

A simple tasty soup to make using leftover ham bone, kidney beans and potatoes. Put it all into the slow cooker in the morning and come home to a savory soup. I have put it all in the slow cooker before bed; turn off in the morning and reheat for dinner - that's the easiest!
1 ham bone with some meat cut off
 1 onion, diced
 1 (14.5 ounces) can peeled and diced tomatoes with juice
2 (15 oz) can of kidney beans  (I add extra can of white beans or one of each)
3 potatoes, cubed
1 bell pepper, seeded and cubed (any color)
6 cubes chicken bouillon

1. Dissolve the bouillon cubes in water, and pour all ingredients in the slow cooker.
 2. Cover and cook on high till warm then reduce heat to low and continue to cook for 6 hours.
**I cook much longer during the night and it has still been delicious
