Prep the veggies: Dice the cucumber, red onion, and bell pepper. Halve the tomatoes. Slice the olives.
Chop the parsley and mint.
Rinse the chickpeas: Drain and rinse the chickpeas under cold water, then pat dry. This keeps the salad from becoming watery.
Make the dressing: In a small bowl or jar, whisk together olive oil, lemon juice, lemon zest, red wine vinegar, garlic, oregano, salt, pepper, and red pepper flakes.
Combine the salad: In a large bowl, add chickpeas, cucumber, tomatoes, red onion, bell pepper, olives, parsley, and mint.
Toss with dressing: Pour the dressing over the salad and toss gently until everything is coated.
Add feta last: Fold in the feta. Taste and adjust seasoning with more salt, pepper, or lemon if needed.
Rest briefly (optional): Let the salad sit for 10–15 minutes to let flavors mingle.
Serve at room temperature or chilled.
