Yoplait has a smoothie product that is really good for you... well it's yogurt of course it's good for you... It comes with the fruit and yogurt all in one packaging. It only has 110 calories per serving. (2 servings per bag)
Another great product from Yoplait is the Yoplait Delights.
You can find these at your local grocer. Yoplait Smoothies is with the frozen foods and Yoplait Delights is located with dairy.
I sounded like a commercial! haha.
