Heat a wok up over a high heat. Add the oil. Once hot add in the beaten egg. Leave to sit in the wok for around 20-30 seconds until it begins to solidify then break it up into small pieces then scrape to one side of the wok. Add in the whites of the onions plus the chilli. Fry for a few seconds.

Add in the prawns. Cook until the water that's released from the prawns evaporates off. Add the msg and white pepper, stir fry with the prawns for a few more seconds. Next add the oyster sauce. Stir to coat the prawns.
