In a large mixing bowl, combine the chickpeas, chopped celery, fresh chives, parsley, and dill.
In a separate small bowl, whisk together the Greek yogurt, mayonnaise, Dijon mustard, lemon juice, salt, and pepper until well combined.
Pour the creamy dressing over the chickpea mixture and gently toss until all ingredients are evenly coated. I sometimes add a little bit of salt or black pepper, but adjust to your taste.
Serve immediately or refrigerate, covered in an airtight container for up to 3 days.
