Some classics are best left as is, like this perfect chicken salad recipe from "Mad Hungry," by Lucinda Scala Quinn.
In a medium bowl, stir together the chicken, celery, parsley, salt, pepper, and lemon juice. Stir in the mayonnaise, little by little, to achieve the desired consistency. The chicken salad can be kept, refrigerated, for 1 day.
Spread butter on each slice of bread. Sandwich with chicken salad and a leaf of lettuce. Serve with salty potato chips.
