(adapted from a recipe at food.com)

3 c diced cooked chicken

1 c finely chopped celery

1 c seedless grapes, halved

1 c chopped walnuts (about 4 ounces or 1/4 lb) (optional)

1 small minced onion

1/2 t salt

1 t Worcestershire sauce

1/2 c mayo

1 t lemon juice

Combine chicken, celery, grapes, walnuts and onion in a large bowl. Mix well. Combine salt, Worcestershire sauce, mayo and lemon juice in a small bowl and mix well. Add mayo mixture to chicken mixture and mix well. Chill for about an hour. (If the chicken was cold to begin with, you don’t need to chill the salad.) Divide lettuce among four plates or bowls and top with chicken mixture. Or add the lettuce to the chicken, celery, grapes, walnuts and onion, and then add the dressing to the chicken and lettuce mixture and mix well.
