Pour both cans of chickpeas (and liquid) into medium saucepan. Simmer over medium heat for 10 minutes, then pour chickpeas into colander or sieve and drain well.
Transfer drained chickpeas to large bowl. Using potato masher or fork, mash chickpeas until desired consistency is achieved.
Add celery, onion, parsley, onion powder, granulated garlic, paprika, mayonnaise, Dijon mustard, and salt to mashed chickpeas. Stir well to thoroughly incorporate all ingredients.
Chill chickpea salad if desired, or serve immediately spooned onto butter lettuce leaves. Drizzle with hot sauce as desired.
