Bring a pan of water to boil and place the salmon in the water. Turn off the heat, cover and allow to sit for 10 minutes. Remove the salmon from the water with a slotted spoon and place onto 4 separate plates.
Steam the asparagus for 3 - 4 minutes.
Spoon the sauce over the salmon and asparagus and serve with small cocktail potatoes.
