The glorious, two-handed sandwich comprises a half-pound tablet of ground pork, veal and duck cooked in its own reduced braising juices and planted between a chewy, crusty roll. Golden haystack onions spill out atop the meat loaf, while a layer of horseradish-dressed frisée packs serious zip, and briny, thin-sliced pickles temper the opulence.

I want that in my mouth, don’t you?
