Mac N Cheese Makeover

I've never met a soul who didn't like macaroni and cheese.  But I have met a few mac n cheese dishes that I didn't like.  Here's one that is not only good to the taste buds but also good to the waste line.  Traditional mac n cheese, made with yummy cream sauce, can be over 1,100 calories just for one main-course serving.  This recipe cuts that in half (493 calories for main course/246 for side dish).  Macaroni and Cheese
