Prep the base. Add the chicken and chickpeas to a large bowl.
Lightly mash about a third of the chickpeas with a fork to help the salad hold together while keeping plenty of texture.
Chop the veggies. Finely dice the celery, red onion, and carrots so they distribute evenly and add crisp bites without overwhelming the salad.
Make the sauce. In a small bowl, whisk together buffalo sauce, ranch, and Greek yogurt or mayo. Stir in lemon juice, garlic powder (if using), and a pinch of salt and pepper.
Combine. Pour the sauce over the chicken and chickpeas. Add the chopped veggies and parsley or chives.
Stir until everything is well coated.
Taste and tweak. Add more buffalo for heat, more ranch for creaminess, or an extra squeeze of lemon for brightness. Adjust salt and pepper as needed.
Chill briefly. If you can, refrigerate for 20–30 minutes. The flavors meld and the texture firms up a bit, making it even better for sandwiches.
Serve your way. Spoon into lettuce wraps, stuff into a pita, roll in a tortilla, or pile onto sourdough.
It’s also great over greens or a quinoa/rice bowl with crunchy toppings.
