one of my mother’s fondest memories spanning the three years she lived in france had to do with this dish. it was her go-to meal at the tiny café she frequented back in the 70s. in its most basic form, a croque monsieur is merely a fancy kind of ham and cheese sandwich. fans of the dish would vigorously disagree with the simplicity implied in that statement. i suggest you make it one afternoon for lunch and come to your own conclusion . . . ‘cause you can’t have my sandwich, that’s for sure.
