Birchermüesli is a Swiss breakfast dish that was invented by Swiss physician Maximilian Bircher-Benner. It is made with rolled oats, grated apples, nuts, and yogurt or milk. The ingredients are mixed together and left to soak overnight, allowing the flavors to meld and the oats to soften. Birchermüesli is a healthy and refreshing breakfast option that is packed with nutrients and fiber. It is often served with fresh fruits and honey, and variations with different ingredients are also popular.
