Split pea and bean soup

Here's a simple variation of traditional split pea soup.  I made this with a ham bone we had leftover from a potluck dinner.  The beans add a nice color and extra oomph.   

Split Pea and Bean Soup

Large onion, chopped
Split peas and water to more than cover
Ham bone with some meat still on it
Salt and pepper
2 cans of beans (I used one can each of Goya's small white beans and small red beans)
Gruyere cheese, optional

Chop and brown your onion.  Cover the bone and the split peas with water in a crock pot and let it simmer all day with the onion.  Before serving, add the canned beans.  Sprinkle the top with some grated cheese if desired.  Gruyere and parmesan are both good with this soup.
