Prep the chicken: Shred or dice cooked chicken into bite-size pieces. Aim for uniform pieces so every bite feels consistent.
Chop your mix-ins: Finely chop celery and onion. Halve grapes.
Dice cucumber and pat it dry to limit extra moisture.
Make the dressing: In a large bowl, whisk Greek yogurt, lemon zest, lemon juice, Dijon, honey, olive oil, garlic powder, salt, and pepper until smooth and creamy.
Add the chicken and veggies: Fold in chicken, celery, onion, grapes, cucumber, and dill. Stir gently to coat everything without smashing the fruit.
Taste and adjust: Add more salt, pepper, lemon, or honey until the balance feels right—bright, savory, and lightly sweet.
Chill if you can: Cover and refrigerate for 20–30 minutes. This helps the flavors meld and the texture set.
Serve your way: Spoon into lettuce wraps, pile onto toasted bread, roll in a tortilla, or scoop over greens or quinoa.
Top with nuts or feta if you like.
