It doesn't get much better than croque monsieur: layers of bechamel, ham and gruyere cheese. Topped with a perfectly poached egg, however, croque monsieur becomes irresistible.it also becomes croque madame.
Croque-Madame ---> grilled ham and cheese on sourdough, topped with Mornay sauce, cheese and a sunny side-up egg! I have no idea what Monday sauce is but I thank goodness for all my chickens. I've been craving eggs!
