In a large mixing bowl, combine the drained and rinsed chickpeas, diced cucumber, halved cherry tomatoes, finely chopped red onion, and diced bell pepper. Toss gently to mix the ingredients evenly.

Add the crumbled feta cheese (if using) and chopped parsley to the salad mixture. This adds a creamy texture and fresh flavor.

In a small bowl, whisk together the olive oil, freshly squeezed lemon juice, minced garlic, dried oregano, salt, and black pepper. Whisking emulsifies the oil and lemon juice, creating a smooth dressing.

Pour the dressing over the salad mixture and toss gently until everything is well coated. This ensures that every bite is flavorful.

Taste and adjust seasoning with additional salt or pepper if needed. Serve immediately or refrigerate for 30 minutes to allow the flavors to meld.
