Chop the vegetables very fine: the cabbage, carrots, and onions are all chopped very fine, almost like the size of rice. You can chop them with a sharp knife, or if you have a food processor with a shredding attachment, use that and then finely chop with a sharp knife.
In a large bowl, combine all the ingredients for the dressing. Whisk until smooth.
Add in cabbage, carrots, and onion; mix well until everything is thoroughly coated.
Cover and refrigerate overnight. Stir it occasionally for the best results. Stir again before serving and enjoy!
