Beat eggs, milk, salt and mustard. Mix well. Into a 13 x 9 inch baking dish, layer the bread cubes, then the sausage and cheese. Pour egg mixture over top and refrigerate overnight. Bake uncovered at 350 degrees for 45 minutes.
Note: Use a 11x7 pan as the casserole is thicker that way. For a 9x13, make 1 1/2 recipes. Can substitute whole wheat bread cubes, turkey sausage and up to half Egg Beaters.
