We had an authentic old fashioned diner in Westfield, New Jersey, the town where I grew up. It was called The Excellent Diner and they had the best chicken salad sandwich ever. I would go after school with friends and I always ordered a chicken salad sandwich on rye toast with lettuce, tomato and mayonnaise. Oh, and a side of well done french fries! It was heavenly chicken salad and I’ve endeavored to recreate it here. It’s not necessary to roast the chicken first but when you do, it gives your chicken salad a wonderful, deep flavor. You can use rotisserie chicken instead of roasting it yourself. This recipe is so easy! I hope you enjoy it. Let me know what you think!.
