In a large mixing bowl, combine the shredded carrots, raisins, and chopped walnuts.

In a separate small bowl, whisk together the Greek yogurt, honey, lemon juice, cinnamon, salt, and pepper until smooth.

Pour the yogurt dressing over the carrot mixture and toss until everything is well coated.

Cover the salad and refrigerate for at least 30 minutes to allow the flavors to meld.

Serve chilled, garnished with additional walnuts if desired.
