I first had this at a friend's house for dinner and loved it. I asked her for the recipe and could not believe it when she said it had mayonnaise in it! She said her Great Aunt made it this way all her life. I never would have posted this recipe because I don't really care for mayonnaise but in this dish it reigns supreme! You've got to try it! I usually use penne pasta and I love adding cayenne, to taste, to the mayo before mixing it in with the pasta.
