Not exactly a recipe, but almost! I have muesli most mornings with milk, plain yoghurt, and sometimes a few blueberries.
I make muesli by going to a health food shop (Goodies and Grains in the Adelaide Central Market, if anyone else is from SA) and looking at one of their packets of sugar/fruit free muesli. Then I buy some of each of the ingredients listed and mix it together at home. I learned early on not to get too much bran as I don't like it much!
I could just buy the one in the packet but its so easy to make and cheaper too.
