Katie's Secret Ingredient Smoothie
This is not an exact science here so I don't have measurements. Having said that, I usually use the following quantities. It makes a blender full.
-3 c. Sprite zero or Diet Twist up (whatever brand of dient lemon-lime soda) <<---psssttt, this is the secret ingredient
-4 scoops Fat Free Rainbow Sherbet (I have only found Wal-Mart brand and its great!)
-2 cups Wal-mart brand's "mixed fruit" frozen fruit (it has mangoes, pineapple, strawberries and peaches in it)
