I followed the recipe on page 171 in the Southbeach diet book for Surprise Southbeach Mashed 'Potatoes' that substitutes cauliflower for potato.
Are you wondering what the surprise is? Wonder no more. The surprise is really no surprise and that it tastes like crap, unless of course you are a fan of pureed, steamed cauliflower doused with fake butter oil and no-fat half and half.
I would rather gain five pounds from eating real mashed potatoes next time.
