Preheat oven to 350.
In a large mixing bowl, mix all dry ingredients.
While mixing with a hand mixer, add apple cider vinegar, boiling water, and egg whites.
Mix for about 15-20 seconds, or just until ingredients are combined and begin to clump together.
Dough will be a bit goopy, almost like oatmeal. (Don't worry, that is normal!)With wet hands, shape dough into eight rolls and place on a greased baking sheet.
Bake for 60-65 minutes, or until bread sounds hollow when tapping the bottom.
For best results, allow bread to cool completely before slicing.
