I adapted this from a similar recipe on recipezaar to suit my low fat diet needs. This is a GREAT base recipe or even great on it's own! You can put virtually anything in this and it's fun to play around with the cheese too...sometimes i sue a parmesan and fontina blend to give it a little bit of a different flavor. I prefer to use Barilla Plus pasta for this. I love the lightness of this cheese sauce, it's a great alternative to Alfredo!
