In a large bowl, combine the broccoli florets, shredded carrots, red onion, raisins, sunflower seeds, and crumbled bacon (if using).

In a separate small bowl, whisk together the mayonnaise, apple cider vinegar, honey, salt, and black pepper until smooth.

Pour the dressing over the broccoli mixture and toss until everything is well coated.

Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld.

Serve chilled or at room temperature.
