I'm not sure if the original Cauliflower Mash came from South Beach, but I know this recipe comes from the South Beach Diet Parties & Holidays Cookbook! I'm diabetic, so always looking for good recipes I can eat without guilt. 12/1/08: We just made this for Thanksgiving, and it was a huge hit. I decided to add 3-4 ounces of fat-free cream cheese (not in the original recipe) for extra creaminess and flavor, and it was a HUGE hit -- even the picky kids gobbled it right down, and there were no left overs.
