Place the olive and sesame oil, stock and soy sauce into a saucepan and bring to the boil.
Reduce the heat to a simmer. Add the salmon pieces to the pan and poach for 3-4 minutes, or until almost cooked through.
Add the noodles to the pan and remove from the heat. Cover with a lid and leave for a few minutes, until the noodles have softened.
To serve, pour the broth into a bowl and sprinkle over the sesame seeds and chives.
