Bring water to the boil, add the noodles and cook for 7 to 15 minutes. Rinse under cold water and drain.
Heat the oil in a wok or frying pan until very hot and stir-fry the squid and prawns for 2 minutes. Add the spring onions, bean sprouts, mushrooms and seaweed and stir-fry for 2 minutes.
Add the noodles and remaining ingredients and seasonings, and stir-fry for 1 minute. Divide the noodles and seafood among four plates and serve.
