Season the chicken with salt, pepper and five-spice
powder. Heat the oil and stir-fry the chicken until
tender. Remove from the pan.
Add the vegetables and
fry until tender but still crisp. Mix the stock with
the remaining ingredients except the chives, stir
into the pan and bring to the boil.
Return the
chicken to the pan and reheat, stirring. Serve
sprinkled with sugar.
