Place the chicken tenderloins into a large pot of salted water and bring it to a boil over high heat. Reduce the heat to low and simmer for 8-10 minutes or until cooked through.
Use a hand mixer or food processor to shred the chicken once it has cooked.
In a large bowl, add the shredded chicken, celery, mayonnaise, onion powder, garlic powder, salt and pepper. Mix until all the ingredients are thoroughly combined.
Fold in the pineapple, grapes, and apples until evenly distributed throughout the salad. Taste for seasoning and adjust if necessary.
Serve the Fruity Fran's Chicken Salad Chick chilled, either on its own or over a bed of lettuce.
