Put the milk, muesli, cocoa, salt, vanilla & a mashed banana in a saucepan and bring the porridge to the boil.
Let it simmer for another 3-5 minutes on a low flame and stir from time to time. Add a little more water if the porridge is too firm for you.
Then pour the porridge into a bowl and spread the delicious blueberry-banana sauce, chocolate chips, walnuts and half a banana over the porridge. Enjoy your meal! :)
