For real ease of preparation, buy a roast duck from a Chinese restaurant (the ones hanging in the window). For a more economical version, roast chicken can be used instead. It’s the freshness of the herbs, crunchy textures and well-balanced dressing that make this salad so delicious.
Place rice vermicelli in a dish or bowl and cover with boiling water. Set aside until soft and cooked through, about 6 minutes.
Drain and rinse under cold water to cool. Use scissors to snip noodles in several places to shorten the strands (this will make it much easier to eat).
Mix all dressing ingredients together.
Reheat duck until warmed through.
In a large bowl, toss noodles, duck and remaining salad ingredients together, and toss with the dressing just before serving. Serve immediately.
