Crockpot Meatloaf

Robert and I have tried tons of meatloafs, either he'd like it an I wouldn't, or visa versa. We both love this one.
I always double this recipe and it works out great!

1 lb ground beef
1 egg
1/2 package of stove top stuffing
1 8 oz can of tomato sauce

Mix ground beef, egg, stuffing mix and 1/3 of the tomato sauce. When it is well mixed shape it in a loaf and put it in the crock pot. Pour the remaining tomato sauce on top. Let cook on high for 3 to 4 hours.
