I know there's a bunch of coffee variations already posted which is where the basic recipe for this comes from, and hopefully I'm not repeating this one here but wanted to share this as I thought it was heavenly.
CARAMEL ICED COFFEE
8-10oz cold water
1 package VANILLA Medifast 55
1 teaspoon instant coffee granules
swig or 2 of Da Vinci Caramel Gourmet Sugarless Syrup
5-6 ice cubes
Blend in blender until smooth.
