This is a basic Chinese vegetable stir fry that can be made with just about any vegetable that can be cooked. Lettuce, spinach, Swiss chard, nappa, bok choy, green beans, asparagus (my favorite), pea pods, broccoli etc are all delicious. Just cut the vegetable properly and, if necessary, blanche before cooking. (Green beans, asparagus & broccoli need 2 - 3 minutes in boiling water).
