Halve the kiwis. Using a teaspoon, scoop out the flesh in the same way you would with a boiled egg. Quarter the pears and slice out the cores. Roughly chop them. Peel and thinly slice the ginger. Roughly chop the spinach.
Add everything to the blender with the coconut water and a cupful of ice. Blitz till smooth and green. Whizz in more ginger if you like.
