This right here is so unassuming but up there with one of the best croque monsieurs i've ever had. Generously buttered and toasted on the bottom, it's stuffed with a mature, very subtly pungent spanish cheese and juust the right amount of bechamel so it's never cloying. (Can't remember if there's ham but there should be, of course lol) Topped with the smallest amount of pickled sliced onions that did so much for the dish by cutting the richness. So simple but immensely tasty.
