Prepare the Dressing: In a large mixing bowl, whisk together the apple cider vinegar, Dijon mustard, and honey until combined. Add the cottage cheese, salt, and black pepper, and mix until smooth and creamy.

Add the Coleslaw Mix: Toss the shredded coleslaw mix into the bowl with the dressing. Mix gently but thoroughly to ensure the dressing evenly coats all the vegetables.

Incorporate the Scallions: Fold in the sliced scallions for a burst of fresh, oniony flavor.

Chill and Serve: For best results, cover and refrigerate the coleslaw for at least 30 minutes before serving. Serve cold as a side dish or a topping for sandwiches and wraps.
