Measure and combine all dry grains and beans (wheat, spelt, barley, millet, lentils, and beans).
Grind the grain and bean mixture in a high-powered grain mill to create a fine, fresh flour.
In a large bowl or stand mixer, combine the warm water, honey, olive oil, and yeast. Allow to proof for 5 minutes until frothy.
Add the fresh milled flour, salt, and vital wheat gluten (if using) to the wet ingredients.
Knead the mixture in a stand mixer equipped with a dough hook for approximately 10 minutes; the dough will likely remain sticky or batter-like compared to traditional breads.
Grease two 9x5 inch loaf pans.
Divide the dough evenly between the prepared pans.
Allow the dough to rise in a warm place for about 60 minutes, or until the dough reaches the top of the pans.
Preheat the oven to 350°F (175°C).
Bake for 45 to 50 minutes, or until the loaves are golden brown and sound hollow when tapped.
Remove from pans immediately and cool completely on a wire rack before slicing. Freeze any bread not consumed within 2-3 days.
