Lighter Chicken Sausage Breakfast Casserole

I LOVE LOVE LOVE breakfast casseroles, the only thing I don't love is the amount of calories per serving. I got a recipe from Taste of Home and made some changes to make it lighter.
I made this casserole for my bestest friend, Amber.  We usually meet for breakfast every other Saturday but this time I asked her to come to my house since I'm trying to watch my caloric intake. We both really enjoyed this lighter recipe!  Tasted just as good as the real thing!  The greatest part about it was the huge serving we got for 311 calories! A great way to start the day! Note - this recipe calls for the casserole to sit overnight.

Ingredients:

15 ounces Isernio's Premium Breakfast Chicken Sausage
1 medium onion, diced
1 1/4 cup egg beaters (you could probably do just one cup if you like the casserole more dry)
2 cups skim/nonfat milk
1 tsp ground mustard
1 tsp salt
1/4 tsp ground pepper
8 slices of Healthy Lifestyle 40 cal per slice bread, cubed
2 cups (8 ounces) reduced-fat shredded cheddar cheese




Directions:

• In a nonstick skillet, cook sausage and onion over medium heat until sausage is no longer pink; drain and cool.  You must allow the meat to cool, if not you will melt the cheese and cook the eggs!
• In a large bowl, beat the eggs beaters, milk, mustard, salt and pepper. Stir in the bread cubes, cheese and sausage mixture. Pour into a 13-in. x 9-in. baking dish coated with cooking spray. Cover and refrigerate overnight.

• Remove from the refrigerator 30 minutes before baking. Bake, uncovered, at 350° for 35-40 minutes or until a knife inserted near the center comes out clean. Let stand for 5 minutes before cutting. 
• Yield: 6 servings for 311 calories per serving OR 8 servings for 234 calories per serving.
