Have all ingredients ready before beginning. Heat 2 tbs. oil in a large frying pan or wok. When oil is very hot, stir-fry the onions and mushrooms for 3 min. Remove to a bowl, and add 6 tbs. more oil to pan. Stir-fry chicken until no longer pink, abt. 5 min. Return the mushrooms and onions to the skillet, and add soy sauce and salt to taste. Remove to a plate and serve immediately. NOTE: the chicken pieces may be marinated for 15 to 30 min. before frying in a mixture of 1 egg white, tsp. cornstarch, 2 tsp. dry sherry, and salt and pepper to taste. This tenderizes the chicken and adds flavor. Sliced water chestnuts and snowpeas may be stir fried with the mushrooms. Recipe: The Continental Key Club, Fairmont, WV
