This is a popular snack in France known as a croque madame (if you omit the egg, it's a croque monsieur). Perfect for breakfast or lunch.
looks absolutely wonderful, must try - but OMG with that fat content should be a twice a year treat!! - 02 Oct 2012
Very tasty and so easy! Just make sure everything you are serving the sandwich with is ready as it cooks so quick! Will definitely make again and again! - 29 Jul 2012
This variant is close to the classic CM, however to reduce the fat content and expand the flavour profile, use sliced Gouda or Edam cheese with a mere smear of Dijon Mustard beneath the good quality ham slices. This item is easy to prepare and consume on a regular basis in our humble household. - 06 Feb 2016
