This recipe from Sunset uses only one pan. Yup, a single pan! The secret is to use frozen cooked shrimp and prepared pesto. When I make it, I thaw the shrimp by putting them in the same colander I am going to use for the pasta. Then I pour the pasta and its boiling water over the shrimp, and--voila--thawed shrimp! The recipe is very pesto-y, so, if you like, feel free to cut down on the pesto and use more sun-dried tomatoes. Also, use whatever pasta shape you like (we prefer long noodles, for instance).
