Stir-Fried Beef with Pickled Mustard Greens

Pickled mustard greens are a staple in southern Chinese cooking. When properly made, they are like the dill pickle, slightly sour but still crunchy, with some texture. Pickled mustard greens are often combined with pork or beef. The meat here is shredded rather than sliced and served on a bed of crisp-fried rice noodles. The noodles combine with the beef mixture to add to the textural quality of the dish. It should be eaten immediately, as the noodles have a tendency to get soggy.
