I'm not sure of the origin of this recipe. My daughter used it in 4-H Food Show competitions in the mid 90s with much success. We have modified it over the years to enhance the nutient value. This is our family and friend's favorite combination, but the recipe is very user friendly and versatile. Feel free to substitute any or all of the fruit, vegetables, and nuts. (zuchinni, pecans, walnuts, dried cranberries, bananas, peaches,etc) I cannot remember ever serving this breakfast muffin to guests who have not asked for the recipe!
