Boil pasta until done. Remove the seeds from the tomatoes and chop the tomatoes into very small pieces and set aside. Start the Alfredo sauce while you are working on the salmon. In a large frying pan cook the salmon until it flakes. Break up the salmon into bite size pieces. Add the cooked pasta and the thickened Alfredo sauce to the salmon and mix it all together. Serve on plates and scatter tomato pieces on top.
