Add all of the ingredients to a dish and whisk together until smooth and creamy.
Place the shredded cabbage in a colander and sprinkle it with 2 teaspoons of sugar and 2 teaspoons of salt. Toss the cabbage to coat it well. Let it sit for 5 to 10 minutes then rinse it with cold water.
Place the cabbage in a salad spinner and spin it dry, or spread it out on a kitchen towel and blot it dry.
Combine the shredded cabbage, carrots, and green onions in a large bowl and toss with enough of the dressing to coat lightly. You may not need all of the dressing. Taste and season as desired.
