Egg Casserole - cooking recipe

Ingredients

5 c. seasoned croutons (seasoned salad croutons or dressing croutons)
5 c. grated Cheddar cheese and Swiss cheese
8 eggs, beaten
1 1/2 tsp. dry mustard
5 c. milk
2 c. canned mushroom soup
1 large jar mushrooms (I cook fresh ones instead)
2 onions, chopped and cooked
2 lb. Italian hot sausage, cooked and added to onions (use hot sauce if you do not use hot sausage)

Preparation

Grease casserole (use a pretty large one).
Layer with croutons, cheeses, cooked sausage and onions.
Mix eggs, mustard, milk, mushroom soup and mushrooms (I season with some curry; it really adds a good flavor).
Pour over top and cover overnight. Bake at 300\u00b0 for 1 1/2 hours or until eggs are set.
Serves quite a few people.
