The sauce is the key to this recipe....HEAVY CREAM, PARMESAN CHEESE, WINE, etc. with CHICKEN & SHRIMP, cooking the penne pasta is the easy part. This recipe makes an ample amount, and too tricky for me to attempt to scale it down. I am posting it to take advantage of Recipezaar's calculations to reduce a recipe. I'm not sure how much this recipe feeds, but I am going to guess at 8-10 servings.
