i forgot...you can use either chocolate, vanilla, or plain protein powder in these bad boys. Casein or whey will work just fine, but be advised that if you use casein you're going to have to mix the water+protein in a blender to get rid of clumps.
Anyone here try Acai (ah-sci-ee)? It's supposed the healthiest fruit in the world. It's loaded with antioxidants and amino acids and whatever else.
Robeks Juice serves an Acai Energy Bowl that's pretty ridiculous. The fruit is made into some ice cream and they throw in bannas and granola. The biggest drawback is it's a bit pricey ($5 a bowl).
