This Low Calorie Peanut Butter Banana Strawberry Smoothie is a great breakfast or meal replacement smoothie!It's just 233 calories and has 6.6g of plant based protein. Plus I added more protein boosts you can choose to add in if you like. Special Tip: If the ingredients don't blend as well as you'd like, add in more almond milk (or water) 2 tablespoons at a time to thin it out.
