INGREDIENTS
1 1/2 cups bulk pork sausage
3 cups herb seasoned croutons
2 1/2 cups shredded Cheddar cheese
4 eggs
2 1/2 cups milk
1 (10.75 ounce) can condensed golden mushroom soup
3/4 teaspoon ground mustard
1/2 cup milk

DIRECTIONS
Brown sausage in a large skillet over medium-high heat; drain fat.
Place croutons in a 9X13 inch baking dish. Sprinkle cheese over croutons; top with browned sausage. Beat eggs and 2 1/2 cups of milk in a mixing bowl, and pour over the casserole. Cover baking dish, and refrigerate overnight.
The following morning, preheat oven to 300 degrees F (150 degrees C). Combine the mushroom soup, ground mustard, and the remaining 1/2 cup milk; pour over the top of the casserole.
Bake, uncovered, until browned and set, about 1 1/2 hours.

Ms Seaside makes this one. Especially good in the winter for holidays, guests. Make the night before and cook while having coffee, bloody marys, whatever.
