Croque-monsieur

A croque-monsieur is a hot ham and cheese (typically emmental or gruyère) grilled sandwich. It originated in France as a fast-food snack served in cafés and bars. More elaborate versions come coated in a Mornay or Béchamel sauce. The emergence of the croque-monsieur (and variations) is mirrored by growth in popular fast-foods in other countries.
