Cook the rice following pack instructions. Boil a separate pan of water and blanch the peas and mangetout for 1 min, then drain and set aside with the rice.

Meanwhile, heat the oil in a large non-stick frying pan or wok over a medium heat and fry the onion for 10 mins or until golden brown. Add the garlic and ginger and fry for a further minute. Tip in the blanched vegetables and fry for 5 mins, then the prawns and fry for a further 2 mins. Stir the rice into the pan then push everything to one side. Pour the beaten eggs into the empty side of the pan and stir to scramble them. Fold everything together with the sesame seeds, soy and vinegar, then finish with the spring onions scattered over.
