Start the night before.
Mix the chia seeds, coconut water and ½ cup still water in a bowl, cover and pop in the fridge over night.
The next morning bring the chia seed mix out and allow to stand at room temperature while you prepare the other ingredients.
In a blender mix the milk , vanilla and yoghurt, and spinach if using then add this blended mix to your chia seed mix and stir thoroughly. You may want or need to add a little extra still water now to get the consistency that you like.
Meanwhile in a dry frying pan gently toast the coconut flakes and almonds.
When ready to serve spoon the chia pudding into a glass and top with a splodge of soy yoghurt and the toasted nuts.
