Wash the zucchini and cut into large pieces. Peel the oranges and cut them into pieces. Remove the leafy greens from one kale leaf from the stem and wash. Wash the persimmons and cut into 4 pieces.
Put all these ingredients in a blender, fill up with water up to the 1 liter mark and mix for 2-3 minutes on the highest level.
If you don`t have kale, you can leave it out and use a medium to large zucchini instead. Then the smoothie gets a much lighter, not so green color.
