You've probably seen muesli cereal at a grocery store. Here's an easy, tasty version you can make yourself.
2-3 cups raw oats
2-3 cups cow's, rice, or soy milk or cream
honey, brown sugar, or agave nectar to taste
handful toasted walnuts
1 sliced apple
Combine oats and milk or cream in large bowl. (Cream makes it really flavorful.) Soak overnight in refrigerator. In the morning, add more milk or cream as needed. Add sweetener, walnuts, raisins, and apple.
