Mix the miso with 1 tbsp soy sauce and stir in the chicken.
Heat the oil in a wok or frying pan and fry the chicken for 3 minutes then add the walnuts and onion and fry for a further 3 minutes. Stir in the pepper and plums and cook for 2-3 minutes until softened, add in the remaining soy sauce off the heat.
Garnish with chopped coriander.
Cooks tip
Great served with rice or noodles. Try using hoisin sauce instead of the soy. This works well with pork fillet too.
