The muesli above is one variation with organic ingredients from Burma, including black sesame seeds, papaya, puffed rice, honey, and fresh yogurt.

Though you can get it in the cereal aisle, it's so much more fun to make it. That way, you can have it just how you like it (you can even make it gluten free!), and you'll know it's fresh. Check out Canadian Living for an assortment of muesli recipes.

Here's the original recipe for one serving of muesli (from Wikipedia), created by a Swiss physician for his patients in his hospital in the early 20th century.

Swiss Muesli
1 tablespoon rolled oats, soaked in 2–3 tablespoons water
1 tablespoon lemon juice
1 tablespoon cream
1 large apple, finely grated and mixed with the above directly before serving
optionally top with 1 tablespoon ground hazelnuts or almonds

Aside from having muesli with milk, try adding it to muffins, breads, or topping yogurt with it and some fresh fruit.
