Start by mixing the mayonnaise or your chosen substitute (like sour cream or Greek yogurt) with salt, pepper, and freshly chopped parsley in a large bowl. This base coats everything beautifully and enhances the salad’s creaminess.
Shred the cooked chicken using two forks instead of chopping it. Shredding creates more surface area for the sauce to cling to, ensuring every bite is flavorful. Add it to the bowl with the sauce.
Quarter the red grapes and dice the celery finely to maintain a balanced texture. Toss these along with the diced red onion and chopped walnuts into the bowl. The grapes add a burst of sweetness, while celery provides crunch, and walnuts offer a nutty richness.
Mix all the ingredients gently but thoroughly, ensuring everything is well-combined. For the best flavor, chill the salad in the fridge for 20-30 minutes before serving to allow the flavors to meld together beautifully.
