Muesli is a cold breakfast cereal dish based on rolled oats and ingredients like grains, nuts, seeds and fresh or dried fruits. This mix may be combined with one or more liquids like milk, almond milk, other plant milks, yogurt, or fruit juice and left for a time to soften the oats before being consumed.
Developed around 1900 by Swiss doctor Maximilian Bircher-Benner for patients in his hospital, muesli is available ready-made in prepackaged dry form, or it can be made from scratch. In Switzerland and Germany, it is also eaten as a light evening dish called Birchermüesli complet: muesli with Café complete.
