A classic chicken salad gets a bright, herbaceous lift from fresh tarragon. This version combines two textures of cooked chicken to create the perfect consistency for sandwiches or scooping. Chopped walnuts add a satisfying crunch that balances the creamy mayonnaise dressing. It comes together quickly for an easy weekday lunch or a light weekend picnic. Serve it piled high on your favorite soft bread or over a bed of crisp greens.
