From the August 2006 issue of Cooking Light, this is one of their lightened recipe makeovers, also one of the magazine's monthly "greatest hits." Very thick, smooth and cheesy sauce with lots of bacon. You won't believe this is the light version! I plan to use the sauce as a base and experiment with roasted red peppers, grilled chicken, shrimp...the possibilities are endless! I used plain old fresh grated Parmesan cheese.
