In a medium bowl, whisk together Greek yogurt, mayonnaise, apple cider vinegar, honey, and salt until smooth. Cover and chill in the refrigerator for at least 15 minutes.

Chop the broccoli florets into bite-sized pieces, core and dice the apples, and shred the carrot.

In a large mixing bowl, combine the broccoli, apples, walnuts, carrots, golden raisins, and red onion. Toss gently until evenly distributed.

Pour the chilled dressing over the salad mixture and gently mix until every piece is coated.

Cover the salad and let it chill in the refrigerator for an additional 10-15 minutes before serving.
