Place the chia seeds in a medium sized bowl and top with water. Stir to combine for a few mins until they begin to swell. Leave to stand for a further few minutes before stirring again to break up any clumps. Add a splash more water if needed as the chia seeds can swell up to 10x their original size and will soak up a lot of water!
While the chia seeds are soaking, place the frozen mango into a blender with a splash of coconut milk and process until creamy.
After about 5 minutes, stir the yoghurt with the soaked chia seeds and add equal amounts of the mixture to 3 jars.
Top the chia pudding mixture with the blended mango and extra mango pieces (optional) before serving.
