1. Bring a large saucepan of water to the boil and boil the egg for 8 minutes. Shock in iced water until cool, then peel the egg, roughly chop it and place in a bowl. Add lime juice and fish sauce and mash everything together with a fork to create a thick, chunky sauce. Stir through a few slices of chilli. 

2. Return water to a boil, add sugar and season water with salt. Add the oil and then the cabbage. Boil cabbage for 2-3 minutes until tender, then remove the cabbage with tongs and drain well. Serve the cabbage with the sauce on the side, or pour it over the top if you prefer.
