Check out Mike's earth oven. Go to the website and you'll see many clear photos of his construction process. I especially like the brick-lined opening that protects the most vulnerable area of the oven from damage.

I can't say very much about the nutritional qualities of Navajo fry bread, but they certainly taste good. Looking at the image of the Navajo elder, I am reminded of the Iraqi woman baking in her tandoor.
