Jimmy Dean Hickory Sausage Breakfast Casserole

1 pkg. Hickory smoke flavor Jimmy Dean Pork Sausage
10 eggs, lightly beaten
3 c. milk
2 t. dry mustard
1 t. salt
6 c. cubed bread
2 c. (8oz) shredded sharp Cheddar cheese
½ t. black pepper
½ c. sliced mushrooms (optional)
1 med. Tomato, seeded and chopped (optional)
½ c. thin-sliced green onions (optional)

Preheat over to 325. In a large skillet, cook sausage over medium-high heat, stirring frequently until thoroughly cooked and no longer pink. Combine eggs, milk, mustard and salt. Distribute half the bread evenly in a butter 9x13x2 baking dish. Sprinkle with half the pepper, half the cheese, half the sausage and half of each optional ingredient. Repeat layering. Pour egg mixture evenly over casserole. Bake uncovered 60 minutes, or until eggs are set. Tent with foil if top begins to brown too quickly.

Absolutely the best sausage breakfast casserole I have ever tasted.
