In a skillet heat millet grains until they turn golden brown. In a large bowl stir together flour, millet flour, baking powder, salt, soda and 2 tablespoons sugar until well blended. Add browned millet grains and raisins. In a bowl mix oil, egg whites, and yogurt until well blended. Pour oil mixture into flour mixture stirring constantly until well blended together.
With your hands pat dough into a ball (if sticky roll in flour) and place on a floured surface. Knead dough lightly 2 or 3 turns, then place on a prepared baking sheet and pat into a smooth circle about 8" in diameter. Using a sharp knife dipped in flour cut into 8 wedges; leave in place. Brush on egg whites and sprinkle with sugar.
Bake 25-30 minutes. Allow to cool 5 minutes prior to serving.
