Being the coffee freak that I am I had to come up with the following recipe since I wont' be at Dunkin Donuts this summer getting my fave drink...
1 Vanilla Medifast Shake
8 oz cold coffee
crushed ice
vanilla extract to taste.
Blend it up and drink. I use a lot of crushed ice to make it nice and thick.
I've also done it with chocolate, it's good.
