Combine all of the above dry ingredients in a large mixing bowl. Add warm water and olive oil, mixing by hand until ingredients are blended. Let rest 5 minutes for grains to absorb moisture.
Turn out onto a floured surface and knead for 5 minutes, adding flour until the dough is soft yet sticky. Roll into a ball and let rise in a greased bowl and cover for 50 minutes. Punch down and let rest 5 minutes.
Knead into 2 long loaves, roll in coarse cracked pepper and sea salt, and place on a baking sheet. Make slits on the top of the loaves with a sharp knife. Let rise 40 minutes. Cook in a 425°F oven for 20 minutes or until the loaf sounds hollow. Remove to cool on a wire rack.
