Method
Mix together all the ingredients for the marinade in a shallow dish. Put the chicken into it, turning to coat it well. Cover loosely with cling film and leave to marinate in the fridge for 30 minutes. Whisk together all the ingredients for the dressing, taste for seasoning and sweet-sour balance and set aside.
Cook the edamame beans in boiling water for 2 minutes then drain and run cold water through them. Slice the sugar snaps into strips along their length (this looks lovely – you can see the little peas inside peeking out). Put these in a broad shallow bowl along with the leaves.
Lift the chicken out of the marinade, shaking off the excess, and heat a griddle pan. Cook the chicken over a medium heat, turning it over frequently, until it is cooked through (this will take about 8 minutes altogether). Cut into strips.
Add the leaves to the salad and toss with the dressing. Either put the chicken on top or serve it alongside. Scatter the chicken with sesame seeds.
Cooking tips
You can get fresh podded edamame beans in supermarkets now, and also frozen ones. If you can’t find them just use more sugar snaps. No need to cook the sugar snaps, by the way, they are gorgeously crunchy and sweet in their raw state.
Japanese food is supposed to appeal to all the senses: how you decorate a dish is of the utmost importance. It’s a thrill to arrange tendrils of pea shoots and mizuna leaves, sprinkle on black sesame seeds and, if I can find them, tiny thread-like micro leaves called red amaranth, arrange slivers of pink pickled ginger and add daubs of green wasabi.
