To make the chicken salad, combine the chicken, celery, green onions, dates, and mayonnaise in a large mixing bowl. If you’re willing, get your hands in there and squeeze everything together. This will break down the dates, and help get the mayonnaise incorporated into the chicken. Season well with salt and pepper. Serve as you please—over a bed of fresh greens, with a side of crackers, or tucked into a buttery croissant or soft roll, or between two slices of freshly toasted bread.
