Awesome Croque Monsieur

Barbara Miller


This is perhaps my favorite "go to" luncheon recipe. They are decadent, tasty, easy and elegant enough to impress anyone's mother in law. Simply serve with fresh fruit, mimosas and a scrambled egg dish and you have a great brunch idea. So many people have asked me for the recipe and you barely need a recipe they are so easy, but don't let that secret out of the bag!
