Cut all vegetables into small (1/4 in) dice and place them in a Crock Pot.
Add all other ingredients (salt and pepper to taste) except parsley. Cover and cook on high heat for 6-7 hours.
Remove ham hock and let cool. Remove meat from the bone, shred, and return to pot. Let simmer another 45 minutes.
Add chopped parsley and serve immediately. If soup appears too thick, add a little more chicken stock to thin it out. Goes great with tomato & garlic bruschetta!
