Prep the produce: Halve the tomatoes, dice the cucumber and bell pepper, finely chop the red onion, slice the olives, and chop the herbs.
Crumble the feta and set aside.
Dress the chickpeas first: In a large bowl, combine chickpeas with olive oil, lemon juice, lemon zest, red wine vinegar (if using), Dijon, garlic, oregano, salt, and pepper. Toss well so the chickpeas start absorbing the flavors.
Add the veggies and olives: Fold in tomatoes, cucumber, bell pepper, red onion, and olives. Toss gently to avoid squashing the tomatoes.
Finish with herbs and feta: Add parsley and any optional mint or dill.
Sprinkle in the feta and give the salad a light toss. Taste and adjust salt, pepper, or lemon.
Let it rest: If time allows, chill for 20–30 minutes. The flavors meld and the salad becomes even more vibrant.
Serve: Enjoy as-is, spoon over leafy greens, or pair with warm pita.
Drizzle a touch more olive oil before serving if desired.
