Jimmy Dean Breakfast Casserole

Preheat the oven to 325° F. In a large skillet, saute the sausages over medium-high heat, stirring frequently, until fully cooked and the pink color disappears. In a large bowl, combine the eggs, milk, mustard, and salt; mix well. Spread half the bread evenly in a 9-inch x 13-inch x 2-inch greased baking dish. Sprinkle with half the pepper, half the cheese, half the sausage, and half of each additional ingredient. Repeat applying layers using the remaining bread, pepper, cheese, sausage and additional ingredients. Pour the egg mixture evenly over the casserole. Bake uncovered for 55-60 minutes or until the eggs are set. Cover with foil if the top starts to brown too quickly. Note: The casserole can be prepared in advance and stored in the refrigerator for up to 12 hours before baking.
