A delicious, nutritious and satisfying muffin from "Cooking Light Magazine (July 2007). You can definitely play around with this recipe- it does well with substitutions. These freeze very well. Either microwave for 20 seconds or just pull one out of the freezer before you leave for the day, and it will be defrosted and perfect in about an hour, just in time for a snack!. If you want, you can fold the flax into the batter, rather than sprinkling it on top.
