Start by gathering all your ingredients. Peel the medium banana and have your frozen blueberries ready for blending.
In your blender, combine the banana and fat-free plain Greek yogurt. Blend until smooth.
Pour in the almond milk and add the frozen blueberries. Blend again until everything is mixed evenly.
Add the 2 tablespoons of PB2 to the blender. Blend until the mixture is completely smooth.
Finally, add the 1/2 cup of ice to the mixture. Blend once more until the ice is crushed and your smoothie reaches the desired consistency.
Pour your Blueberry Banana PB Smoothie into a glass or mason jar. Enjoy this refreshing drink immediately!
