In a large mixing bowl, combine the drained chickpeas, diced cucumber, halved cherry tomatoes, finely diced red onion, chopped parsley, and crumbled feta cheese (if using). Toss gently to mix the ingredients evenly.

This combination of ingredients provides a variety of textures and flavors, making the salad more enjoyable.

In a separate small bowl, whisk together the olive oil, lemon juice, minced garlic, dijon mustard, salt, and black pepper until well combined.

Whisking emulsifies the oil and vinegar, creating a smooth dressing that coats the salad evenly.

Pour the dressing over the salad and toss gently to coat all the ingredients.

Taste and adjust the seasoning with more salt or pepper if needed.

Serve immediately or refrigerate for 30 minutes to allow the flavors to meld.
