Top the piece of salmon with 1 tsp of sweet chilli dipping sauce and grill for 6 - 8 mins till the salmon is cooked through and the sauce starts to char. Delicious, quick and low fat
NB Have just read your question properly and realise this is not what you're asking! The above is good with boiled Thai rice and French beans though!
I agree with Shaneystar, cous cous is a quick easy accompaniment. I roast vegetables to mix in it. If you are not particularly kitchen minded the Ainsley Harriot range of cous cous comes ready flavoured, the Citrus Kick one would be good with salmon
