Brown sausage, drain and crumble. Place croutons in a 10 x 6" dish; spread sausage and cheese over croutons.
Combine two eggs, 1 1/2 cups milk, 1/3 c. chopped green pepper and pour over sausage. Cover and refrigerate overnight. Blend one can Cream of Mushroom soup, 1/4 cup milk and pour over casserole. Bake at 300 degrees for 45 - 60 minutes. Let stand five minutes. Very good!!!
