Rinse and drain the canned chickpeas. Pat them dry with towels to remove any excess moisture, then place them in a large bowl.
Dice the cucumber, red bell pepper, and red onion. Quarter the cherry tomatoes and chop the olives.
Add the cucumber, red bell pepper, cherry tomatoes, crumbled light feta cheese, red onion, and Kalamata olives to the bowl with the chickpeas. Toss gently to combine.
In a separate small bowl, whisk together the lemon juice, olive oil, crushed garlic, Dijon mustard, oregano, basil, parsley, salt, and pepper until combined.
Pour the dressing over the salad and toss thoroughly until everything is evenly coated.
Transfer the salad to an airtight container and chill it in the refrigerator for at least 30 minutes, or until ready to serve, to let the flavors meld together.
