Soak the noodles in warm water for 7-10 minutes, rinse in cold water and drain thoroughly.
In a pestle, grind together the garlic and chillies into a coarse paste and mix in the sugar, fish sauce, sesame oil and lemon juice.
Place the noodles, turkey and vegetables in a large bowl and pour the chilli-garlic dressing over. Toss lightly. Sprinkle the coriander and spring onions on top and using your fingers toss again with a light touch. Serve.
