Bring a large pot of salted water to a boil. While this is coming to a boil prepare the remaining ingredients. When the water comes to a boil, add sugar snap peas and cook for about a minute or until crisp tender. Retrieve them from water with a sieve and run under cold water to stop the cooking. Pat dry and set aside. Add pasta to water and cook until al dente, about 8 to 10 minutes. When pasta is done, drain and refresh under cold water. Pat dry. Combine in a bowl with green onion, mustard vinaigrette, smoked salmon and parsley. Season well to taste with salt and freshly ground black pepper.
