food
inconvenient truth: the same plant that produces prickly pears is also the source of nopales, but you can't get both from the same plant because nopales have to be harvested before the fruit grows and the plant can't grow fruit after you take off the nopales (in fact I think it dies and has to be replanted?)
re: food
@Felthry wikipedia says prickly pears and nopales are the same thing?
