Combine first 3 ingredients in a large bowl; stir. Add water, yogurt, and honey; stir. Let stand 30 minutes. Add beans and next 12 ingredients (beans through vinegar); stir. Stir in 4 1/2 cups bread flour to form a soft dough.
Turn the dough out onto a floured surface. Knead until smooth and elastic (about 8 minutes); add enough of remaining flour, 1 tablespoon at a time, to prevent the dough from sticking to hands. Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85°), free from drafts, 45 minutes or until doubled in bulk.
Punch dough down. Divide dough into 4 equal portions, and shape each portion into a 6-inch round loaf. Place loaves 4 inches apart on large baking sheets coated with cooking spray. Make 4 (1/8-inch-deep) diagonal cuts across tops of loaves. Dust loaves with flour. Cover and let rise 45 minutes or until doubled in bulk. Bake at 375° for 25 minutes or until loaves sound hollow when tapped; let cool on wire racks.
