1 cup Frozen Berry Medley (I use the one from Trader Joe’s that has Blueberries, Blackberries, Strawberries, and Raspberries), but you can also just use frozen Strawberries, frozen Blueberries, etc. – pretty much any combination of berries that you like.
1/2 cup Unsweetened Vanilla SoyMilk: you can use any brand you like, but just make sure it’s unsweetened – and has only 0-1g sugar and 100 calories for 1 cup. For a creamier smoothie with more protein, use 1 cup soy milk.
Stevia or Agave sweetener, to taste (optional)
