In a large mixing bowl, combine the broccoli florets, shredded carrots, chopped red onion, dried cranberries, and sunflower seeds.

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

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

Chill in the refrigerator for at least 30 minutes before serving to allow flavors to meld.
