I was introduced to this wonderful flavor idea at the cafe in the gym at school. At first it sounded a bit odd, but after my first sip I was hooked. Obviously I had to try it out at home as there is no way I could go all summer without another one. So here is what I came up with:
1 cup frozen mixed berries
1/4 cup apple juice (or enough to help it blend)
1 spoonful of peanut butter
Puree the ingredients in a blender and serve!
