I have a serious comfort food association with chicken salad sandwiches. Particularly in summer.That's when Mom made them for me for lunch. And I don't mean salads WITH chicken (the "ugh" of the healthy menu at fast-casual restaurants). I mean the sloppy, sticky diner-style chicken salads all gloopy with mayonnaise, speckled with sweet pickle relish and studded with crunchy bits of chopped celery.
