In a large mixing bowl, combine the finely shredded cabbage, grated carrot, diced apple, and thinly sliced red onion. This mixture will provide a crunchy texture and a balance of sweet and savory flavors.

In a separate bowl, whisk together the mayonnaise, apple cider vinegar, honey, salt, and black pepper until smooth. This dressing will coat the vegetables and add creaminess and tang.

Pour the dressing over the cabbage mixture and toss well to combine, ensuring all ingredients are evenly coated. This step is crucial for flavor distribution.

Let the coleslaw sit for at least 10 minutes before serving to allow the flavors to meld together. This resting time enhances the taste.

Serve chilled or at room temperature as a side dish or topping for sandwiches.
