Not diet food. So rich. So creamy. Decadent. Make it. Enjoy it. I've made this 3 times now and my family just loves it. I made it to serve at the big family Christmas, too. Not your traditional orange "Mac and Cheese". From "Everyday Italian" show on Food Network. The original recipe claims 8 servings, but we get more like 8 from a 3/4 recipe. I would say it does 12 servings. It is very rich.
