250g chicken thighs, skinned and boned
A handful of cress
1 1/2 tablespoon dashi-nomoto
2 tablespoons caster sugar
3 tablespoons mirin
4 tablespoons shoyu
2 onions, sliced thinly lengthways
4 large eggs, beaten
4 spring onion (cut into 6cm length)

2.Place the 300ml water in a frying pan and bring to a boil. Add the dashi-nomoto, sugar, mirin and shoyu, simmer for 1 minute.
3.Add the onion slices into the pan and lay the chicken pieces on top. Cook over a high heat for 5 minutes, shaking the pan frequently.
4.Sprinkle the spring onion and cress when the chicken is cooked. Pour the beaten eggs over to cover the chicken. Cover and wait for 30 seconds. Do not stir.
5.Remove from the heat and leave to stand for 1 minute. The egg should be just cooked but still soft, rather than set. Do not leave it so that the egg becomes a firm omelette.
6.Scoop the warm rice into a bowl, and then pour the soft eggs and chicken on to the rice. Serve immediately.
