I like that it is so customizable. You can use your favorite cheese - cheddar, Swiss, Colby-jack, American - or any combination to your liking. Chopped sweet onion and sweet pickle relish really add great flavor too! Don't you just love flexibility in a recipe?
And for those watching their carbs, this is a protein-packed power treat without the bread. Add some chopped celery or sweet peppers, and serve on salad greens for a healthy and tummy-pleasing lunch.
