Sweet Potato Souffle

Prepare to be wow'ed (I was last Thanksgiving, when my friend A. made this for me and I couldn't stop eating it).  This sweet potato souffle will have you coming back for seconds, and maybe even thirds.  It's easy to throw together, and bakes up perfect for Sunday dinner.  NOT to be missed at your Thanksgiving feast this year, make note!
