In truth you want to avoid mueslis that have a high wheat content and go for ones that are mainly (or solely) oats. Then add milk and give them a couple of minutes in the microwave as the heat makes it easier for the body to break them down and absorb the goodness (you could just have porridge of course).
Hold on, hot muesli?
I’ve only ever eaten it with cold milk – don’t tell me I’ve been doing it wrong for 40 years?
