In a small mixing bowl, combine the olive oil, lemon juice, dill, garlic, salt, and black pepper. Whisk the ingredients together vigorously for about 30 seconds until well blended and emulsified.

In a large salad bowl, add the chickpeas, chopped cucumber, cherry tomatoes, and red onion. Gently mix these ingredients together for about 1 minute.

Pour the prepared dressing over the salad mixture and toss gently to ensure all ingredients are coated without breaking up the chickpeas or cucumbers.

Serve immediately or chill in the refrigerator for about 30 minutes to enhance flavors before serving.
