01 - Preheat the broiler or grill to high heat. Place red bell peppers directly under the broiler or on the grill, turning occasionally, until skins are charred and blistered, approximately 10 minutes. Transfer to a bowl, cover with plastic wrap, and let steam for 5 minutes.
02 - Peel and discard charred skin, remove seeds, and slice the peppers into thin strips.
03 - In a large salad bowl, combine chickpeas, roasted pepper strips, cucumber, red onion, cherry tomatoes, basil leaves, and olives.
04 - In a small bowl or jar, whisk together olive oil, lemon juice, garlic, oregano, salt, and pepper until emulsified.
05 - Pour the dressing over the salad and toss gently to combine. Top with crumbled feta cheese if desired. Serve immediately or refrigerate for 30 minutes to allow flavors to meld.
