Shiitake mushrooms with mung bean sprouts

Wash 7 or 8 mushrooms, cut off and discard stems, cut caps into ¼ strips, stir-fry in oil about a minute then add the washed and drained sprouts (12 oz. package), continue frying, then add a splash of balsamic vinegar and a sprinkle of salt and stir fry for 7 or 8 minutes until the mushroom flesh is no longer white but the sprouts aren't soft.
