Step 1 Place hoisin sauce and 2 tablespoons cold water in a medium bowl. Add chicken. Toss to coat. Heat a large frying pan over a medium-high heat. Cook chicken, pouring over any remaining marinade, for 4-5 minutes each side or until cooked through.

Step 2 Meanwhile, place noodles in a small heatproof bowl. Cover with boiling water. Stand for 5 minutes or until noodles are tender. Separate noodles with a fork. Drain. Refresh under cold water.

Step 3 Combine noodles, two-thirds of the onions, and the remaining ingredients in a large bowl. Toss to combine. Serve chicken with sesame coleslaw and sprinkle with the remaining onion.
