Even if you won't be climbing any mountains or sailing any seas, you'll need to fuel up before heading out. Made entirely of organic whole grains, two kinds of nuts, and dried fruit, this classic muesli provides all the staying power you need.

Muesli may have been created over a century ago by a Swiss physician for his patients, but the reasons for eating it remain the same: It's nourishing, minimally processed, and offers a load of health benefits. This traditional muesli is made with rolled oats and rolled wheat, walnuts and almonds, and raisins and dates, all certified organic, and with no added sugar or other sweetener.

To prepare it as the good doctor intended-and how countless Swiss families still choose to do-simply soak the muesli overnight in your milk of choice so it's perfectly plumped and creamy in time for breakfast. Of course, you can also just tumble into a bowl and top off with cold milk, or even let it steep in hot water for a comforting start to the day. Muesli also makes a satisfying snack when sprinkled over yogurt. However you choose to enjoy it, remember to say thanks to Dr. Bircher when you do.
