Using a food processor, dice your cabbage, carrots and onion. Alternatively, you can use a hand grater/shredder.
In a medium bowl combine all of your dressing ingredients. Whisk well until smooth and creamy.
Drizzle your dressing over the shredded cabbage mixture, toss well to combine.
Chill in the fridge, covered, for at least 2 hours, or overnight before serving.
Enjoy!
