Crock Pot Sausage and Potato Soup

I threw this in the crocko before I left for work this mornin...it was super good...4 out of 5 approved! (And middle kid never approves)! It's easy, it's stuff I had on hand, and used stuff from my freezer so that was good too!  It goes like this...add the following to a crock (I used my 7 qt.)
1lb. of ground meat, browned and drained.  (I don't care what it is, beef, turkey, deer, anything!)  (I used sausage, hence the name)
about 4-6 medium potatoes cubed
shredded carrots( I bet I used a cup, I had them frozen from the garden in 2 cup packages and used half)
4 c. of chicken stock
1 chopped onion (I keep onion chopped in the freezer)
4T. of butter
1/4c flour
and whatever seasonings you please, we are plain eaters so I used celery salt (you could use celery), and salt and pepper, and some parsley
I turned my slow cooker to "warm" and left it all day.  I think 6 hours on low would be good. When you get home or 30 minutes before serving add:
8 oz. of shredded cheese (I used velveeta, cause that makes everything better)
11/2c. of milk or cream. 
and simmer until the cheese is melted!  It sounds like a lot but with all the stuff from the garden, I didn't buy a thing for this...and it was REALLY good! 

PS: Photo was before I left for work...pre cheese and milk!
