Prep the chickpeas: Drain and rinse chickpeas under cold water.
Pat them dry with a clean towel to help the dressing cling better.
Chop the vegetables: Dice the cucumber and bell pepper. Halve the tomatoes. Thinly slice the red onion.
Halve the olives.
Make the dressing: In a small bowl or jar, whisk together olive oil, lemon juice, lemon zest, garlic, oregano, Dijon, salt, and pepper until emulsified.
Combine the base: In a large bowl, add chickpeas, cucumber, tomatoes, bell pepper, red onion, and olives.
Add herbs and feta: Sprinkle in parsley, mint (if using), and crumbled feta.
Dress the salad: Pour the dressing over the mixture and toss gently until everything is well coated.
Taste and adjust: Add a pinch more salt, pepper, or lemon juice if needed. If you like more richness, drizzle another teaspoon of olive oil.
Rest (optional): Let the salad sit for 10–15 minutes to let the flavors meld. Serve chilled or at room temperature.
