Mix the soy, sesame oil, chilli and ginger together and coat this over the salmon. Allow this to marinate for about ½ an hour.
Heat the oil in a non stick frying pan and fry the salmon cubes on each side until just cooked through. Or, if you prefer these a little rare, leave them raw on the inside.
Cook the noodles according to the manufacturers instructions, drain and toss in the pesto.
Top the noodles with the salmon, spritz with lemon or lime an dgarnish with fresh coriander leaves.
