1. In a large mixing bowl, combine the whole wheat flour, sprouted spelt flour, and sprouted barley flour.
2. Add the cooked and mashed lentils, cooked millet, honey, and salt. Mix well.
3. Dissolve the yeast in warm water and let it sit for about 5 minutes until frothy.
4. Pour the yeast mixture into the flour mixture and stir until a dough forms.
5. Knead the dough on a floured surface for about 10 minutes until smooth and elastic.
6. Place the dough in a greased loaf pan, cover, and let it rise in a warm place for about 1 hour or until doubled in size.
7. Preheat the oven to 375°F (190°C). Bake the bread for 45 minutes or until golden brown and sounds hollow when tapped.
8. Remove from the oven and let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
