This is sooo delish! And on top of that, it's guilt-free! It's only 109 calories and no fat! This is so incredibly like the ice cream/sherbet bars of long ago! Well, let this rock you into the past, with flavor and memory! Soooo Goood!
Place all ingredients in a martini shaker, but DO NOT shake(or the carbonated soda will explode!). Mix thorougly with a spoon until mixture is mostly lump-free. Add about 1 cup ice (crushed, if you have it), and stir until mixture is cold. Then place the strainer on top and pour into a large martini glass. Enjoy!
