Preheat oven to 350. Prepare chicken breasts for baking by using meat hammer to get them to fairly even thickness. Sprinkle chicken breasts with salt, pepper, and other seasonings of choice. Line a baking pan with foil and put chicken breasts in. Cover with foil on top and create foil packets by closing the foil pieces around the chicken. Bake for around 15-25 min depending on size of chicken. While chicken is baking prepare all other ingredients. Mix the mayonnaise, vinegar, honey, and sugar first. Then fold in the pecan halves, cranberries, and celery. Note: 4 cups of cooked chicken is around 3 lbs of chicken breasts raw.
