A very good smoothie, and without a banana, which I don't always want in my smoothies. I used a mix of frozen unsweetened berries (black, blue, straw) and subbed some cherry extract for the vanilla, since I used low-fat sugar free vanilla yogurt. I also cut the recipe down to serve 2. I will try it again in larger amounts and try freezing it to take in the RV, where I hate trying to use a blender. :) Made for Spring 2008 PAC.
