I cheat and use the yoplait frozen smoothie mix. Quite expensive, but my insides won't allow me to eat as much fruit as I'd like, so the fruit goes bad. These smoothies you just add milk and I usually add more than called for because they are so thick you can almost eat them with a spoon. Ok, now I'm ready for one. Biggest Losers approves of these. The package actually makes two servings.
