Thaw the salmon, wash, dab with kitchen paper and cut into bite-sized cubes. Cook the pasta in salted water (according to the instructions on the package) and then strain.
Heat a large pan with a little oil or margarine and fry the pieces of salmon in it (approx. 3 - 4 minutes), turning in between. Pour in the cream. Stir in vegetable stock, tomato paste and horseradish and season with dill and pepper. Let simmer gently for approx. 1 - 2 minutes.
Then add the noodles to the sauce in the pan and mix everything until all the noodles are covered with sauce. Serve sprinkled with parmesan.
