And if you have cooked vegetables left over from the night before, chop 'em up and toss them in, too. In fact, you could sliver almost any leftover and stir it in. I wouldn't actually worry too much about a sauce -- if you're already putting in slivered meat, eggs, etc., there'll be plenty of flavor. Maybe a little broth+cornstarch, but even that's not totally necessary.
