Yes! We recommend meal prepping the chicken ahead of time, either by making some slow cooker shredded chicken or breaking down a rotisserie chicken from the store. Chop or shred your cooked chicken into bite-sized pieces, then store it in the fridge until you're ready to mix your chicken salad. When you're ready to eat, toss the cold chicken in with the dressing, grapes, and cucumbers! Store any leftovers in the fridge.
