In a large bowl, combine the chickpeas, celery, pepperoncini, and enough dressing to coat nicely; toss gently.
Let this marinate for about 30 minutes.
When ready to serve fold in most of the parsley and the dill.
Taste for more dressing.
Meanwhile, place the avocado in a small bowl along with the lemon and a pinch of salt; toss very gently to coat.
Gently fold as much avocado into the salad as you’d like.
Serve immediately, topped with the remaining herbs and a drizzle of the dressing or olive oil.
