Luke Nguyen grew up on this very authentic southern Vietnamese recipe for noodle salad, which makes a perfect light lunch. "Bun" is the vermicelli noodles, "bo" is the beef and "xao" means to stir-fry – the beef is quickly marinated and charred in a hot wok and served on top of cold noodles, cucumber, beansprouts and herbs. You simply add nuoc cham and garnish to taste.

Cook's notes

Oven temperatures are for conventional; if using fan-forced (convection), reduce the temperature by 20˚C. | We use Australian tablespoons and cups: 1 teaspoon equals 5 ml; 1 tablespoon equals 20 ml; 1 cup equals 250 ml. | All herbs are fresh (unless specified) and cups are lightly packed. | All vegetables are medium size and peeled, unless specified. | All eggs are 55-60 g, unless specified.

Instructions

Marinating time 10 minutes

Combine the beef with 2 tbsp of fish sauce, half the garlic and a little of the lemongrass. Marinate for 10 minutes.

Put the noodles into bowls and top with the bean sprouts, cucumber and most of the herbs.

Heat the oil in a wok over high heat and add the onion and remaining lemongrass. Stir briefly then throw in the beef, allowing it to char and develop a smoky flavour. Add the extra fish sauce and remove from the heat. Add the beef to the bowls and sprinkle with the remaining herbs. Garnish with pickled vegetables, peanuts and fried shallots and dress with nuoc cham.
