Our version of the croque-monsieur seems to be a grilled cheese with ham, which is pretty similar to the croque-monsieur just without the sauce. The croque-monsieur directly translated to “crunch-mister,” which is sometimes taken as “eat this, man.” There are variations, including cheese or eggs on top.
I picked the croque-monsieur because I thought the name was funny, but as a side note I really love croissants and crêpes. :)
