Add all ingredients into your blender. I add them into my blender in the order that is listed in the ingredients. While the order probably isn't vital, at the very least, you should put your liquid in first.
Begin to blend your ingredients. Since I used frozen strawberries, I switch to the "ice crush" setting briefly once the strawberries hit the blades in order to properly mix them in. Then, continue to blend until the smoothie is at your desired consistency.
Pour into glasses and serve immediately.
Notes
For extra protein and added healthy fats, you can also decide to add in other mix ins, such as protein powder and ground flax seed, which are things I usually do (which is why they are listed as optional ingredients).
