Chicken Pasta with Alfredo Sauce

I might go on a diet soon where I don't eat sugar or flour, but... 

Walmart sells a large frozen chicken pasta with Alfredo sauce that I really like. So I wondered if I could make something similar at home. I occasionally cook a whole box of penne pasta and then mix it with a 22-ounce jar of Alfredo sauce. This is really delicious. Sometimes I would add chicken, but it is very good by itself. 

Of course, I don't eat all of it at once; I store the leftovers. 

 However, I ran out of Alfredo sauce, so I tried mixing the pasta with a 16-ounce container of "Classic Chicken Salad" that I got at Aldi. It turned out to be fantastic! The chicken salad has enough sauce to coat the pasta.
