I got this recipe from the Skinny Bitch recipe book. I highly recommend reading their books if you are considering becoming a vegan.
The recipe is super easy and fantastic!
2 cups of frozen fruit
1 cup of soy/almond/whatever you want milk
Simple as that. I throw flax seed, wheat germ, and this amazing meal stuff in mine. Mainly because I drink smoothies as a meal and want to get as much as I can from it.
