Wash the broccoli florets under cold running water and transfer to a large mixing bowl.

Dice the apple and add it to the bowl with the broccoli.

Add shredded carrots, raisins or dried cranberries, and sunflower seeds to the bowl.

In a separate bowl, whisk together Greek yogurt or mayonnaise, apple cider vinegar, honey, salt, and pepper until smooth.

Pour the dressing over the broccoli mixture and gently fold until everything is evenly coated.

If desired, incorporate finely chopped red onion; mix again.

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes.
