Mom's breakfast casserole

My family wakes up to this yummy casserole every Christmas morning. Wouldn't start a holiday any other way.

Ingredients:

6 eggs

2 cups milk

3 slices of bread, cubed

1 lb ground sausage

1 tsp salt

1 tsp dry mustard

4 oz shredded cheddar cheese

Brown sausage. Beat eggs; add milk, salt, and mustard; beat again. Add bread cubes, cheese and sausage; stir. Put in a greased 9x13 baking dish (but I use a smaller square pan for a thicker casserole), cover with foil, and refrigerate overnight. Remove foil and bake for 45 minutes at 350 degrees, or until egg is set and casserole is brown around the edges.
