Add all of the ingredients, except the water, to a medium bowl and whisk to combine. Add the water, 1 tablespoon at a time, until your desired consistency is reached (I use all 3 tablespoons of water).
Add the cabbage, cucumber, spring onion and red onion to a large bowl. Top with the dumplings. Pour the dressing over, toss to coat, then add the coriander leaves and peanuts to garnish. Drizzle over more chilli oil crisp, if using.
