Tim says pretty much just throw stuff in until it tastes good. With that said, here is a guess at a recipe.
Put all ingredients in blender. Cover and blend on high speed about 30 seconds or until smooth. Pour mixture into 3 glasses.
Notes: Apple Juice works as a good base instead of OJ. You also might want to try raspberries, peaches, blueberries, or any other fruit you have available.
