Start by chopping your cooked chicken into bite-sized pieces. Dice the hard-boiled eggs, celery, pickles, and green onions. Chop the fresh dill finely so its flavor spreads evenly throughout the salad.
In a large mixing bowl, combine the chicken, eggs, celery, pickles, green onions, and dill. Gently stir to mix everything without breaking up the chunks of chicken or eggs.
Stir in Greek yogurt, Dijon mustard, and white wine vinegar. Season with sea salt and black pepper. Taste and adjust seasoning, adding more pickles or mustard if you want a stronger flavor punch.
You can serve the salad immediately, but chilling it for 30 minutes helps the flavors meld beautifully. Keep it covered in the fridge if you’re prepping ahead of time.
Serve the salad in lettuce leaves or on a plate. Garnish with extra fresh dill or sliced green onions for a vibrant, fresh presentation.
