what does "poke-greens"mean?
Jody heard nothing; saw nothing but his plate. He had never been so hungry in his life, and after a lean winter and slow spring, with food not much more plentiful for the Baxters than for their stock, his mother had cooked a supper good enough for the preacher. There were poke-greens with bits of white bacon buried in them; sand-buggers made of potato and onion and the cooter he had found crawling yesterday; sour orange biscuits and at his mother's elbow the sweet potato pone. He was torn between his desire for more biscuits and another sand-bugger and the knowledge, born of painful experience, that if he ate them, he would suddenly have no room for pone. The choice was plain.
