Boil the rice following pack instructions, adding the peas for the final min. Drain.
Heat half the oil in a wok. Pour in the egg and stir-fry until scrambled. Tip onto a plate and set aside.
Wipe the wok with kitchen paper, then heat the remaining oil. Toss in the meat, garlic, spring onions and pepper, and stir-fry until the pepper starts to soften. Add the five-spice, rice, peas and soy, then stir-fry for 5 mins more. Finally add the beansprouts, if using, the egg and prawns, and stir-fry to heat through.
