Crock Pot Shepherd's Pie

Ingredients:

2 lbs of hamburger
1 chopped yellow onion
2 cans Cream of Celery soup
1 C green beans
1 C corn  (again, we used mixed frozen veggies)
6 C mashed potatoes
2 C grated cheddar cheese

Directions:

-  Brown hamburger and onion
-  Combine meat mixture, veggies and soup together
-  **  At this point, we freeze the mixture for later use!  :)
-   Place mixture in crock pot
-   Place mashed potatoes on the top.  (We used instant potatoes for simplicity's sake!)
-   Cover the top with cheese
-   Cook on low for about 6 hours
-   Remove the cover for the last 30 minutes or so to allow the extra liquid to evaporate from around the edges.
