In a large mixing bowl, combine the shredded cabbage, shredded carrots, and sliced red bell pepper.

In a separate bowl, whisk together the apple cider vinegar, olive oil, honey, Dijon mustard, salt, and black pepper until well combined.

Pour the dressing over the vegetable mixture and toss until all the vegetables are evenly coated. Let it sit for at least 10 minutes before serving to allow the flavors to meld.
