Mix together the orange juice and sweet chilli sauce.
Place the salmon on a non-stick baking sheet and spoon over half of the sweet chilli mix.
Roast for 20 minutes until the salmon is cooked and just starting to brown.
Place the noodles in a large heatproof bowl, cover with boiling water and set aside for 5 minutes or so. Drain the noodles and cool under water. Stir in the reserved sweet chilli sauce mix. Add the red onion, cucumber, chilli, ginger, coriander and sesame seeds.
Divide between bowls and top with the salmon - either whole or broken into flakes.
