Which one would you go for?
At risk of being contentious, I wouldn't choose any of them - lovely as they look. This is partly a personal thing as I've never understood granola and muesli for breakfast. I don't understand how they are supposed to be 'healthy' as they tend to contain sugar or honey. In particular the store bought versions can contain high amounts of sugar.
As a kid I had porridge every morning - but no sugar. Just a little milk and salt.
