Granny Smith Apple And Sausage Breakfast Casserole

1 package pork sausage roll
6 cups whole wheat bread, cubed
3 cups skim milk
10 eggs
1 teaspoon vanilla
1 teaspoon salt
2 large Granny Smith apples, peeled and chopped 
1 teaspoon cinnamon
2 tablespoons sugar
2 cups cheddar cheese, divided 

Grease a 9x13 inch baking dish while preheating oven to 325 degrees.
In a large skillet, brown the sausage and drain. Set aside.
In a large mixing bowl, whisk together the milk, eggs, vanilla and salt.
In another large mixing bowl, mix together the apples, cinnamon and sugar. Make sure the apples are well coated.
In the prepared baking pan, layer half the bread crumbs on the bottom and then half the sausage, half the apples and then 1 cup of cheese. Continue to repeat layers until ingredients are gone.
Take the egg mixture and pour evenly over the layers.
Bake for 1 hour or until hot and bubbly.
