In a small non stick saucepan add the sesame oil and the ginger and garlic. Cook on a medium heat for a few minutes. Then add the teriyaki sauce, soy sauce, honey, pepper and chilli flakes and let bubble for a few minutes. Take off the heat and add the chicken. Leave it to stand for half an hour or so. Then cook the chicken in a hot wok or saucepan until it bubbles and turns sticky and gorgeous.
