A healthier alternative to mashed potatoes and a great way to sneak veggies into your kids. I made this for my boyfriend (a previously self-proclaimed cauliflower hater) and my mother who both thought they were eating potatoes. Mom, who is a somewhat picky eater, said she liked this even better than mashed potatoes! I did omit the wasabi for her. Originally using low-fat sour cream, I now use greek yogurt or a mix of the two.
