This recipe is adapted from a friend's--it makes hearty, moist muffins that are good for South Beach Phase 2 because they have no refined carbs or sugar--just oats, oat bran, flax seed, and walnuts. I make them for my partner who has high cholesterol. The flax seed substitutes for oil/butter and also makes them really fluffy; for SB you can substitute fresh/frozen blueberries or cranberries for the craisins. Note: These are NOT SWEET--they are more like a walnut-fruit bread than a sweet muffin, we prefer this. You can make them sweeter by using vanilla soy milk, but that adds sugar to this no-sugar delight. The fruit is also optional--I've made them with just walnuts and they are still delicious. Enjoy!
