Thoroughly rinse and drain chickpeas in a colander. For extra texture, pat them dry with paper towels.
Dice the cucumber, halve the cherry tomatoes, chop the bell pepper, and finely dice the red onion. For milder onion flavor, you can soak your diced red onion in cold water for 5 minutes, then drain thoroughly before using.
In a small bowl, whisk together olive oil, fresh lemon juice, minced garlic, dried oregano, salt, and pepper until emulsified.
In a large bowl, combine chickpeas, cucumber, tomatoes, bell pepper, red onion, Kalamata olives, feta cheese, parsley, and mint.
Pour the dressing over the ingredients and gently toss until everything is evenly coated.
Allow the salad to rest for at least 15-30 minutes before serving to let the flavors meld together.
