Healthy Chicken Salad Sandwiches are sensational! Instead of using mayonnaise or Miracle Whip, this recipe uses Icelandic skyr yogurt. It’s so much better and thicker than Greek Yogurt. This recipe includes walnuts, red grapes, red bell pepper, celery and red onion. It’s crunchy and absolutely delicious when garnished with mild bell pepper rings. Great for tailgating parties. The chicken salad without croissants is gluten free.
