Spray a medium non-stick frying pan with oil to grease. Heat over medium-low heat. Add bok choy and 1 tbs water

Cook until vibrant and almost tender. Transfer to a plate. Add green onions, ginger and chilli to pan. Cook, stirring, for 1 minute or until tender

Add egg mixture to pan and swirl to coat pan base. Cook without stirring for 30 seconds

Using a wide spatula, push the set eggs around the outer edge towards the centre of the pan, tilting pan to allow the uncooked eggs to run over the base

Gently push eggs around pan every 15 seconds until soft folds form and one quarter mixture is unset. Remove from heat. Add bok choy and serve with a drizzle of oyster sauce
