I use smart balance too! Also Parkay spray..no calories! Well if you chugged a bunch it probably would, lol. I love sweet potatoes too, I like to mash them with Splenda and cinnamon and top with a little sugar free syrup and chopped pecans! Yummy! Can't have them right now though, I', Level 1. :(
I overdid it on the sweet potato cassarole on Thanksgiving anyways. And the day after..naughty me.
