Add frozen mango and kiwi, ginger, protein powder, to a blender and blend for about 1 minute, or till combined and smooth. Taste and add maple syrup, if needed.
Notes
If you can't find a frozen mango/kiwi blend, try 1 1/4 cups of frozen mango and 1 frozen kiwi, or just use all mango.
This was tested with 1 scoop of pumpkin seed protein powder. I recommend a mild flavored protein powder.
This recipe has a kick. If you don't like a lot of ginger spice, decrease the amount to 1-2 teaspoons.
