Wash the broccoli thoroughly and chop it into bite-sized florets. Core and dice the Honeycrisp apples into small cubes. Finely chop the red onion.

In a large mixing bowl, combine the chopped broccoli, diced Honeycrisp apples, and red onion. Add sunflower seeds and dried cranberries, and gently toss together.

In a separate bowl, whisk together Greek yogurt, honey, and apple cider vinegar. Season with salt and pepper to taste.

Pour the dressing over the salad ingredients and carefully toss until everything is well-coated.

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes before serving. Toss again before plating.
