Sweet potatos are considered occasional indulgences I believe. I like one two weeks or so. They make great fries, and I doubt you really need a recipe for them.
Just cut one into fry-like strips, and fry it in coconut oil. Keep them to a small amount in the pan at a time, or they will do more steaming than frying, and be soggy. Cook them at fairly high heat. If you want a little extra crunch, roll them around beaten up egg whites before you fry them, and salt them ahead of time so some of the moisture will draw out.
I couldnt find any recipes for fries, but I did find this one for chips, which is about the same thing. http://www.marksdailyapple.com/apple...-potato-chips/
