Add the chopped broccoli florets, pickled red onion, dried cranberries, sunflower seeds, and shredded cheese (if using) to a large bowl.
In a small bowl, whisk together the dressing ingredients until smooth.
Pour the dressing over the broccoli mixture and toss well to coat.
Cover and refrigerate for at least 30 minutes before serving. This helps the flavors meld and slightly softens the broccoli.
