Here's one I love. Get:
8 egg whites
5 splenda packets
2 tablespoons of instant coffee
1 cup water
Put in the blender anf enjoy this fat-free, carb free, protein packed, caffeine packed iced coffee! Sure it's not the best in the world, but very acceptable on a low carb/fat diet! You can also replace egg whites with vanilla whey i you wish.. Even add some cottage cheese for more creamier taste.
