Squeeze the sausages out of their skins. Mix the sausagemeat with the garlic, ginger and red chilli, then fry in the sesame oil until browned. Add the green beans, then fry for 1 min more.
Tip in the straight-to-wok noodles and a splash of soy sauce, and toss together. Add a splash of water and put the lid on to allow the beans to steam for a couple of mins. Sprinkle with fresh coriander leaves and sesame seeds to serve.
