Creating this amazing vinegar coleslaw is straightforward when you follow these steps:

1. Prepare the Vegetables: Finely shred the green and red cabbage using a sharp knife or a mandoline slicer. Grate the carrot and set them aside in a large mixing bowl.

2. Make the Dressing: In a separate bowl, combine the apple cider vinegar, granulated sugar, salt, black pepper, and celery seeds. Whisk until the sugar dissolves completely.

3. Combine Ingredients: Pour the dressing over the shredded cabbage and carrots in the mixing bowl. Toss well to combine, making sure all the vegetables are evenly coated.

4. Add Green Onions: If using, stir in the chopped green onions for an extra layer of flavor and crunch.

5. Chill (Optional): For the best results, cover the coleslaw and refrigerate for at least 30 minutes. This chilling step allows the flavors to meld beautifully.

6. Serve: After chilling, give the coleslaw a good stir before serving it alongside your favorite summer dishes.

By following these simple steps, you’ll have an incredible vinegar coleslaw ready to impress your guests.
