Prepare the veggies: Drain and rinse the chickpeas thoroughly under cool water, then let them dry in a colander. Meanwhile, halve the cherry tomatoes, dice the cucumber, and slice the red onion very thin. If the onion is strong, soak the slices in cold water for 5 minutes, then drain to mellow the flavor.
Mix up the salad base: In a large mixing bowl, combine the chickpeas, cherry tomatoes, cucumber, red onion, olives, and crumbled feta cheese. Add the parsley and mint, and gently toss the ingredients together with a wooden spoon or silicone spatula.
Whisk the dressing: In a small bowl or mason jar, whisk together the olive oil, red wine vinegar, lemon zest, lemon juice, garlic, oregano, and a generous pinch of salt and pepper. If using a jar, just shake it up until emulsified.
Toss and chill: Pour the dressing over the salad and gently toss again to coat all the ingredients evenly. Let the salad sit for 10–15 minutes before serving — this helps the flavors really soak in.
Serve it fresh: Enjoy the salad chilled or at room temperature, as a side dish, light lunch, or stuffed into pita pockets. Optional: top with extra feta or a drizzle of tahini for extra richness.
