In a small bowl, combine the ingredients for the sauce and mix well.
Heat a wok over medium fire. Add the lard. Once the wok is almost smoking, fry the garlic. When the garlic turn a light brown, add the sausages and prawns. Turn the heat to high and fry.
Once the prawns are almost pink, add the bean sprouts and noodles. Add the sauce, a pinch of salt and white pepper to taste. Fry for 1 minute. The noodles will have soften a little.
Make a hole or push the noodles aside. Crack the eggs and stir to break the yolk. Add a pinch of salt onto the eggs. Cover the eggs with the noodles. Add the chives. Once the egg has almost set (takes about 10-15 seconds), stir to combine. Take a quick taste. Add more salt or soy sauce if necessary. Serve immediately.
