A traditional sandwich from New Orleans, Louisiana, made with a long roll of French bread and containing a variety of fillings, almost always with some kind of meat or fried seafood. ("Po' boy" being short for "poor boy," supposedly referring to striking workers in 1929 to whom a local restaurant served such sandwiches.) Primarily heard in US. Ever since leaving New Orleans to go to college, I can't stop craving a proper roast beef po' boy from back home. I'm ordering a dozen po' boys for the party, so if you have any food allergies, let me know this afternoon.
