Preheat the oven to 425 degrees Fahrenheit. Place the chicken breasts on a cookie sheet and generously coat them with olive oil, salt, and pepper.
Cook the chicken in the preheated oven for approximately 45 minutes or until a meat thermometer inserted into the thickest part reads 165 degrees Fahrenheit.
While the chicken is cooking, prepare the vegetables by dicing the onion, green pepper, and celery.
Once the chicken is done, let it rest for 10 minutes, and then use two forks to shred the meat. Place the shredded chicken and diced vegetables into a mixing bowl and sprinkle with white pepper.
In another mixing bowl, combine the cool whip, miracle whip, and chicken bouillon granules to create the dressing. Mix well until all the ingredients are thoroughly combined.
Add the dressing to the chicken and vegetable mixture, ensuring everything is evenly coated. Place the bowl in the refrigerator for at least one hour to allow the flavors to meld together. The longer it chills, the better the flavors will blend.
Just before serving, wash the grapes and cut them in half. Add them to the chicken salad, providing a burst of sweetness and texture.
Serve the chicken salad on a croissant with some shredded lettuce or in a cream puff for a delightful twist. Alternatively, you can enjoy it on its own or with your favorite bread or crackers.
Sit back, savor each bite, and appreciate the harmonious blend of flavors in this unique chicken salad recipe.
