The name shortens 'mea 'ono pua'a,' Hawaiian for 'delicious pork thing' — plantation-era locals scaled up the Chinese char siu bao into a bigger, sweeter, Hawaii-only version.
A fist-sized bun of soft white dough is stuffed with sweet char siu pork, then steamed or baked and kept hot in warming cases at corner stores and lunch wagons across the islands. Chicken, curry, and hot dog versions are now just as common as the classic pork filling.
