This power smoothie tastes kind of like a dreamsicle. It is packed with protein, fiber, and vitamins, and it's sugar free. Try to get Wildwood brand unsweetened soy yogurt, as it is the only plain soy yogurt I know of that is sugar free. Unsweetened vanilla extract is available at most health food stores.
- Place everything in a blender and blend on high speed until very smooth and creamy.
