Place chia seeds in a container and add coconut milk, coconut water and a drop of vanilla extract. With a spoon stir until well combined. Close the jar with a lid and leave to soak for about 2 hours. You can also refrigerate overnight, but keep in mind your coconut milk will thicken to almost solid and will have a denser consistency.
Peel and cut mango into chunks and put into a blender. Add juice of 1 lime to blender. Blend until smooth and thick.
Assemble your pudding: place a couple of spoons of mango puree, then add a layer of chia pudding and repeat. Top your pudding with macadamias, coconut yoghurt or other garnish of choice. Serve and enjoy!
