Prep the chicken. If using rotisserie, remove skin and bones, then chop or shred the meat into bite-size pieces. If using cooked breasts or thighs, cool before cutting to keep the texture firm.
Make the dressing. In a large bowl, whisk together mayonnaise, Greek yogurt, Dijon mustard, lemon juice, and honey. Add a pinch of salt and a few grinds of black pepper.
Add the crunch. Stir in the diced celery and minced red onion.
If using fresh herbs, fold them in now for the best flavor.
Combine with chicken. Add the chicken to the bowl and gently mix until everything is evenly coated. Taste and adjust seasoning—add more lemon for brightness, more mayo for creaminess, or more pepper for a little kick.
Customize. Fold in any optional add-ins you like: grapes for sweetness, apples for crisp bite, pickles for tang, or nuts for toasty crunch.
Chill briefly. Let the chicken salad rest in the fridge for 20–30 minutes. This helps the flavors meld and the texture firm up, making it easier to spread.
Toast the bread. Lightly toast your bread or warm your croissant.
This adds structure and keeps the sandwich from getting soggy.
Assemble. Lay down lettuce or spinach on one slice to act as a moisture barrier. Spoon on a generous layer of chicken salad. Top with the second slice of bread and press gently.
Slice and serve. Cut diagonally for classic lunch vibes.
Add a side of fruit, chips, or a simple green salad to round it out.
