Meanwhile, cut the onion, tomatoes and olives into small cubes and pluck the salmon into small pieces.
Heat some olive oil in a pan, fry the onions until translucent and then add the tomatoes, olives and salmon. Fry everything for 1 - 2 minutes over medium heat, then add the cream cheese and stir. Season with salt, cayenne pepper and basil and turn off the heat.
Drain the pasta and add to the pan with the remaining ingredients. Mix everything briefly, arrange on a plate and pour a few more splashes of olive oil over it.
