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. The oats are soaked in water or milk overnight, and then mixed with grated apples, yogurt, and a sprinkle of nuts. Birchermüesli is a refreshing and filling breakfast option that is often enjoyed with a cup of hot coffee or tea.
