Bring the oats to the boil with the milk and a pinch of salt in a small pan, then keep cooking over a low heat.
Mash half the banana directly in the pan and stir it into the porridge until it turns creamier.
Stir in the chia seeds and linseed and let everything simmer gently until it reaches the consistency you like.
Take the pan off the heat and fold in the peanut butter to make the porridge especially rich.
Roughly chop the walnuts and slice the rest of the banana.
Spoon the porridge into a bowl and serve with banana, walnuts, honey or maple syrup, cinnamon and, if you like, cacao nibs and blueberries.
