Chicken Apple Sausage Egg Strata

This is a variation on the egg strata I posted earlier. It's really good and really easy.

1 lb precooked chicken/apple sausage, without casings
6 eggs beaten
2 cups skim milk
6 pieces whole grain bread, heels removed
1 cup Swiss and Gruyere shredded cheese (I got this mixture at Trader Joe's)

Cut sausage in small pieces. Remove heels from bread and cube. Beat the eggs with the milk, then add bread and sausage. Place in slightly greased casserole dish (9 x 13). Cover with shredded cheese. This must sit overnight in the refrigerator. In the morning, cook at 350 degree oven for 45 minutes. It serves at least 8 people, sometimes more.
