Prep the produce: Dice the cucumber and bell pepper, finely chop the red onion, slice the olives, and chop the parsley. Rinse and drain the chickpeas well so the salad doesn’t get watery.
Make the dressing: In a small bowl, whisk together lemon juice, lemon zest, olive oil, garlic, Dijon, dried oregano, a pinch of salt, and black pepper until slightly thickened and glossy.
Combine: In a medium bowl, add chickpeas, cucumber, bell pepper, red onion, olives, and capers (if using).
Pour over the dressing and toss gently to coat.
Add the herbs and feta: Fold in parsley and crumbled feta. Taste and adjust salt, pepper, or lemon as needed. If you like heat, add a pinch of red pepper flakes.
Rest (optional but ideal): Let the salad sit for 10–15 minutes so the flavors mingle.
If you have time, cover and chill for 30–60 minutes.
Serve: Enjoy as-is, spoon over greens, stuff into pita, or pair with grilled chicken or fish for a bigger meal.
