Just 4 ingredients! No added sugar or artificial ingredients! This Low Calorie Peanut Butter Banana Spinach Smoothie is here to make your New Year’s resolution a breeze.
Place all ingredients in a blender, Magic Bullet or Nutribullet. I use a Nutribullet because it processes it finer and it’s already in a cup to go!
Notes
If you don’t have, or can’t find, PB2, you can substitute 2 tablespoons of natural creamy peanut butter but it will add 165 calories and 2 grams of protein. You can further slash the calories by using unsweetened almond milk, but you will also forgo some of that filling protein.
