Slow Cooker Ham Bone Soup

Combine 8 cups water and bouillon cubes in a slow cooker; stir until bouillon is dissolved. Add tomatoes, beans, ham bone, potatoes, onion, and leftover ham. Cook on Low until ham is coming off the bone, about 8 hours. Taste and add another cup of water if too salty.

When the soup is almost done, bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water, stirring occasionally, until tender yet firm to the bite, about 8 minutes.

Drain macaroni and add desired amount to the soup.

Remove ham bone. Shred meat and discard bone. Return meat to the soup, stir to combine, and serve.
