Cool chicken breast, and chop into small bite-sized pieces.
Place chicken, cranberries, miracle whip, onions, celery, and cayenne into a bowl and stir well.
Place one cup salad onto a croissant roll, and serve. Repeat with remaining salad. Should make 4 sandwiches.
You may substitute Mayonnaise instead of Miracle whip, but you will need to add salt and pepper to taste. Chicken salad can be made up to three days before using. It is best used fresh.Omit the onion or celery, or blend it fine before adding, to make it more kid-friendly!
