A cheap and cheering street snack that consists of wheat dough wrapped around any of a variety of fillings, such as minced pork mixed with chopped fennel or a vegetable called shepherd's purse, flattened into a disk and toasted on a skillet. Another delicious snack is jian bing, a thin crêpe spread with beaten egg, fermented sauce, chile paste, and chopped scallions, and then wrapped around a piece of crisp, deep-fried pastry.
