First, wash the spinach thoroughly, then chop the apple and banana.
Next, cut the avocado in half, remove the pit, and scoop out the flesh.
Then, place all of the ingredients into a blender.
After that, blend for one to two minutes, until completely smooth and even in texture.
If it seems too thick, add a little more almond milk.
Finally, drink it fresh, ideally right after making it.
If you're craving a more intense, fresher flavor, add a little grated ginger as well. Instead of walnuts, you can also use almonds or cashews, so you can easily change up the flavor without having to make an entirely new recipe.
