Looking for recipes using ham bones without any dried beans or peas in them, I found another one.

Corn Soup with Potatoes and Smoked Ham

Saute until vegetables are tender, about 10 minutes.
Add corn and stir 5 minutes.
Add ham hock and potato, then 5 cups water; bring to boil.
Reduce heat to medium-low; simmer partially covered 1 hour.
Remove ham hock.
Season soup to taste with salt and pepper.
