Birchermüesli is a Swiss-style muesli that was invented by Swiss physician Maximilian Bircher-Benner. It is a healthy and refreshing breakfast dish made with rolled oats, grated apple, yogurt, and nuts. The ingredients are mixed together and left to soak overnight, allowing the oats to soften and the flavors to meld. Birchermüesli is often served with fresh fruits and honey, making it a nutritious and delicious way to start the day.
