Ham and Potato Soup

HAM AND POTATO SOUP

4 medium potatoes, diced
1/4 - 1/2 C diced ham (I use lunchmeat ham and it works well enough :)
3 stalks celery, chopped
2 carrots, chopped
1/2 C onion, diced
4 C chicken/vegetable broth (if you don't want it really brothy then just ad 3 1/4 - 3 1/2 C)
1/2 tsp garlic salt
dash of pepper
dash (small) of thyme

4 Tbsp butter
4 Tbsp flour
2 C milk

I just put the vegetables/ham in the crock pot with broth and seasonings.  Cook for a few hours on high.  When vegetables are tender then make the roux with the butter, flour and milk.  Add to crock pot and cook a little longer on low.
