Poached Chicken, Hazelnut, Watercress and Pea Salad

A simple salad like this relies on the best and very freshest ingredients. Buy the most expensive, high-quality chicken that you can afford – you be glad you did once you’ve tasted the finished product. If you can’t get hold of lemon grass, then use the equivalent amount of finely grated lemon zest in the dressing and use lemon peel in the poaching liquor.
