Put the porridge oats and water in a pan and bring to the boil and then simmer for 2 minutes before placing with a lid on in the simmering oven. Leave overnight. It will taste like it has been made with cream! Add honey and fruit to serve.
If you do not have an aga just simmer the porridge on the top for 10 minutes, stirring as you go.
If you need to pack in more nutrients you can of course make this with milk, there are so many delicious, dairy free options now, so if you want to keep it dairy free try coconut, hazelnut or almond – all are in our supermarkets.
