Birchermüesli is a Swiss breakfast dish that is made with rolled oats, grated apples, yogurt, and nuts. It was invented by Swiss physician Maximilian Bircher-Benner in the late 19th century as a healthy and nutritious meal. Birchermüesli is often enjoyed with a drizzle of honey or a sprinkle of cinnamon. It is a refreshing and energizing way to start the day.
