Prepare the dressing: In a small bowl, whisk together Greek yogurt, apple cider vinegar, honey, Dijon mustard, salt, and pepper until smooth.
Mix the salad: In a large bowl, combine broccoli, diced apple, dried cranberries, nuts, and red onion.
Toss it all together: Pour the dressing over the salad and toss to coat everything evenly.
Chill & serve: Refrigerate for at least 30 minutes to allow flavors to blend. Serve cold.
