The low-carb faux mashed potatoes made with cauliflower is something my guys liked - my picky eater son even asks for it!
My husband *loves* those. He was part of a weight loss challenge in the last 3 months of last year, and he missed potatoes so much, so I made the cauliflower for him with a really low fat mushroom gravy. He was in heaven. Now that the challenge is over, we still do cauliflower instead.
(oh yeah, he won. 70 lbs in 3 months!)
