Boil the rice with the sliced ginger for 25 mins until tender – use just enough water so that it cooks, but it’s not swamped. Drain well and remove the ginger.

Heat 2 tsp oil in a large wok, then stir-fry the chopped ginger, pepper and garlic for about 1 min. Tip in the beansprouts, spring onions, carrots and chilli, if using, then stir-fry until the veg has softened and started to char. Remove from the heat.

Stir the miso with 2 tsp water to dilute it a little, then beat in the eggs. Heat 1 tsp oil in a large non-stick frying pan. Pour in half the egg mixture and scatter over half the rice. Allow the mixture to set to an omelette. While still a little moist, tip half of the vegetables on top and cook for a few seconds more. Carefully roll up, and repeat with the remaining egg, rice and vegetables.
