Fry the sausage in a fry pan and use as the final layer over the bread and cheese. Mix the eggs, milk and salt and beat. Pour the egg mixture over the bread, cheese and sausage layers. Cover and refrigerate the entire mixture overnight.
Bake in a 350 degree oven 45 - 50 minutes, place a water bath on the lower shelf of the oven.
