Breakfast Casserole

This is such an easy recipe!  It can be cooked either in the oven or in the slow cooker.  When I make it for dinner, I usually put it in the slow cooker.  It's also our traditional Christmas morning breakfast, and for that I make it in the oven.  I'll put the recipe for both versions here...

6 - 8 biscuits, cooked and torn into pieces
1 pound ground sausage (we like it with sage sausage)
1 1/2 c. milk
6 eggs, beaten
2 c. shredded cheddar cheese
1 tsp. dry mustard

Oven: Mix all ingredients except 1 cup of cheese; pour into baking dish that has been coated with non-stick spray; top with remaining cheese; cover and refrigerate overnight.  Bake at 350 for an hour.

Slow Cooker: Mix all ingredients except one cup of cheese; pour into slow cooker that has been coated with non-stick spray; top with remaining cheese; cover and cook 2 hours on high, then 1 hour on low.
