I started making my own muesli several years ago. It's a lot cheaper than store-bought muesli and has less fat and no high fructose corn syrup. You can add or delete ingredients to your taste.
3 or 4 cups old fashioned oats (you may toast them for a stronger flavor)
1/2 cup flax seed
1/2 cup wheat germ
1/2 cup raw pumpkin seeds
1/4 cup sesame or sunflower seeds (or both)
1/2 cup nuts (i like pecans)
1/2 cup raisins, dried cranberries, figs or any other dried fruit
1 tablespoon cinammon (may also use ginger powder, nutmeg or allspice)
optional add-ins:
brown sugar to taste
protein powder
Put ingredients in sealable container. Shake. Nice served with fresh fruit and milk or plain yogurt.
