Muesli is a cold breakfast dish made from a mixture of rolled oats, nuts, seeds, and dried fruits. It is often served with milk, yogurt, or fruit juice, making it a nutritious and convenient meal option. Muesli is popular for its high fiber content and can be customized with various ingredients to suit individual tastes. Originally created by Swiss physician Maximilian Bircher-Brenner in the early 1900s, muesli was designed as a healthy food for patients. Today, it is enjoyed worldwide and is available in many commercial varieties, often with added sweeteners or flavors.
