Boil the rice following pack instructions, adding the peas for the final minute. 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 garlic, spring onions and pepper, and stir-fry until the pepper starts to soften. Add the five-spice, beansprouts, rice, peas and soy, then stir-fry for 5 mins more. Finally, add the egg, chorizo (if using) and prawns, and stir-fry to heat through.
