If your blender is not a high-speed blender, chop the smoothie ingredients into bite-sized pieces, including the greens.
At the bottom of the blender, place 3 ice cubes with the lemon juice, ginger, and greens at the bottom of the blender. Blend well.
Add in the banana, avocado, kiwi, tangerine, and coconut butter.
Blend again until completely smooth. The consistency should be like soft-serve ice cream.
If you prefer a drinkable consistency for your green smoothie, add in the liquid and process again until fully blended.
Divide among two bowls, sprinkle with the toppings of your choice, and enjoy!
