Prepare the Vegetables: Slice the cabbage into thin strips using a sharp knife or mandoline. Grate the carrot and cut the onion into thin rings.

Mix Together: Add the cabbage, carrot, and onion to a large bowl and toss to combine.

Prepare the Dressing: In a separate bowl, whisk together apple cider vinegar, olive oil, honey, Dijon mustard, celery seed, salt, and black pepper. If you prefer a sweeter dressing, feel free to add extra honey to taste.

Combine and Coat: Drizzle the dressing over the shredded vegetables and mix well to ensure everything is evenly coated.

Marinate: Let the coleslaw sit for at least 15 minutes in the refrigerator to allow the flavors to meld.

Final Stir: Give the coleslaw a final toss before serving to redistribute the dressing.

Enjoy: Serve chilled as a side dish or topping for your favorite meals.
