Bacon Asparagus Strata:
Prepare as above, except replace sausage with 8 strips of bacon that have been crisp-cooked, drained, and chopped, and replace mushrooms with one 9-oz. package frozen cut asparagus, thawed and well-drained. Combine bacon, asparagus, and red peppers in a medium bowl rather than a skillet. And, use 12 ounces of shredded Swiss cheese in place of the American cheese.
