IMPOSSIBLE BREAKFAST PIE

1 lb. bulk pork sausage (I prefer hot/spicy)
2 cups milk
1 cup shredded cheddar cheese
1 cup Bisquick
6 eggs
1 tsp. dry mustard
1/2 tsp. oregano leaves

Brown and drain sausage.

Mix sausage with remaining ingredients and pour into a 2 quart casserole (or double it and use a 13x9-inch baking dish). Cover and refrigerate overnight.

Preheat oven to 350 degrees F.

Bake uncovered for about 1 hour or until a knife inserted in the center comes out clean.
