Kidney Bean Salad

The bean, walnut, celery, and olive mixture can be combined up to 24 hours in advance and refrigerated in an airtight container. Add the mayonnaise dressing just before serving to maintain the best texture and prevent the salad from becoming watery.

Store the dressed salad in an airtight container in the refrigerator for up to 2 days. Note that the celery will soften and walnuts will lose some crispness over time. Stir before serving and add a tablespoon of fresh mayonnaise if the salad appears dry.
