Try the salmon sauce. It's easy as hell and tastes awesome.
First of all, slice and dice some onion, a small salmon cutlet and a tomato per serving. Add a little oil in a frying pan and as soon as it's hot, add the onion and some salt over it. When it gets golden, add the tomato and stir until the tomato starts to melt. Add the salmon, stir a little more until it gets cooked (try not to overcook it or will be VERY dry), add your favorite spices (black peeper, parsil and oregano are the best for this recipe) then add to the pasta of your choice.
Protip: you can buy the tomato already on a can peeled and diced. Saves a lot of time. Also, let the salmon completely de-frost for an hour or more if you buy it frozen before slicing it.
