Soak the noodles in a heatproof bowl of boiling water for 1 minute, then strain and set aside. Heat 2 tablespoons of the vegetable oil in a wok or frying pan (skillet) over a high heat, add the beaten eggs and fry for a minute on each side, without stirring, until they set like an omelette. Transfer to a plate, then cut into thin strips. Heat 1 tablespoon of the oil in the wok or frying pan over a high heat, add the carrot, pepper, baby corn and mangetout with a splash of water to stop them burning and fry for a minute. Transfer to a plate. In the same wok or frying pan (you don’t need to clean it) add the remaining tablespoon of oil, then add the onion with a splash of water, the curry powder, chilli powder (if using – I use mild curry powder and leave out the chilli powder when I’m cooking this for kids) and garlic powder or granules and fry for a couple of minutes over a high heat until the aromas are released. Toss in the cooked vermicelli and put all the vegetables back in the wok or pan. Toss again so everything is evenly distributed. Add the soy sauce, sesame oil and egg strips and keep frying and tossing until the noodles change to a golden yellow colour. Taste and season with salt and pepper as needed, add the spring onions and serve.
