Whisk the dressing. In a large bowl, whisk together the olive oil and pomegranate molasses.
Add everything and season. Add the chickpeas, red onion, tomato, cucumber, bell pepper, walnuts, parsley, and mint. Sprinkle the sumac, cumin, salt, and pepper over the top.
Mix and rest. Toss until every chickpea is coated. Let sit 10 minutes so the flavors meld.
Serve. Drizzle with extra pomegranate molasses if you like and serve with crispy pita.
Notes
Sumac is the key spice. If unavailable, add extra lemon and a pinch of za-atar.
For the classic Lebanese version, skip the pomegranate molasses and walnuts.
