Hash Brown Breakfast Casserole in the Crock Pot

This is the recipe Sue Grunig fixed for us the last morning at Johnson's cabin. It was excellent and especially convenient as we were busy packing and cleaning up but we still had a hot breakfast.

Hash Brown Breakfast Casserole
30 oz. frozen hash browns, shredded
Cooked sausage (I think diced ham or bacon would be good too)
12 eggs
1 c. milk
1/2 diced onion
1 1/2 c. grated cheese
1 t. kosher salt
1 t. pepper
Spray crock pot. Dump in hashbrowns. In mixing bowl combine; eggs, milk, onion, cheese, salt & pepper. Stir well and add the meat. Pour over the hash browns. Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours. It's done when the eggs are cooked and the edges start to brown.
