Prepare the casserole the night before.

In a 9x13 inch casserole dish, place 8 slices of bread to cover the bottom.

Place 8 slices of Italian sausage (or more) to cover the bread.

Add 8 slices of sharp cheddar cheese over the sausage.

Cover with another layer of 8 slices of bread.

Layer with more Italian sausage to cover the bread.

Layer the top with slices of cheese.

In a mixing bowl, beat 6 large eggs.

Add 1/2 teaspoon salt, 1/2 teaspoon black pepper, 1/2 teaspoon dry mustard, 1/4 cup minced onion, 1/4 cup finely chopped green pepper, 1/4 cup finely chopped sweet red pepper, 2 teaspoons Worcestershire sauce, 1/8 teaspoon Tabasco sauce, and 3 cups whole milk.

Mix well to blend the egg mixture.

Pour the egg mixture over the prepared casserole.

Cover with plastic wrap and refrigerate overnight.

The next morning, preheat the oven to 350F.

Remove the casserole from the refrigerator and remove the plastic wrap.

Melt 1/2 cup butter and spoon it over the top of the casserole.

Cover the top with 3/4 cup crushed corn flakes or Special K cereal.
