In a bowl or serving glass combine all the ingredients for the chia porridge and stir. Place in the fridge (preferable the night before enjoying it) stir one time before you go to bed. The nest morning you have a lovely and creamy porridge. Serve with your favourite fruit in season – and a splash of heavy cream (so good).
