You can make this with bacon, ham, or sausage but I always use sausage because it is easier for me. You assemble this the night before and just pop in the oven in the morning. This is great for holiday mornings because it can bake while you are doing other things.
Brown 1 pound sausage and drain.
Beat 6 eggs and add 1 t. mustard, 2 cups milk and salt/pepper.
Cube 4-6 slices of bread. (I use regular sliced white bread but you could use what you have.)
Line sprayed 13X9 baking dish with cubed bread.
Top with cooked sausage.
Sprinkle with 1 package shredded cheddar cheese.
Pour egg mixture over top.
Cover and refrigerate until morning when ready to bake.
Bake 350 for 30-45 minutes until set.
