Heat oil in a non-stick fry-pan and cook the salmon fillets for approximately 10 mins, turning once. Once cooked, gently flake salmon into a bowl.
In a saucepan with boiling water, add a pinch of salt and cook the pasta until tender. Drain and return to the pan.
Add the flaked salmon, yoghurt and tomatoes and gently mix through. Gently reheat until warmed through, for 3-5 mins.
Serve with a salad.
