The name of these empanadas, like so many things, just sounds better in Spanish.
Empanadas de Pollo, Puerro, y Pimiento--it's almost like a tongue twister school kids would recite for better diction. (Pepe Pecas pica papas con un pico. Con un pico pica papas Pepe Pecas. Pepe Pecas picks potatoes with a pick. With a pick picks potatoes Pepe Pecas.)
Or it could be a phrase learned on a Spanish language cd--I can almost hear the velvet-voiced narrator say it: "Listen and repeat: Empanadas de Pollo, Puerro y Pimiento."
