In a large bowl, dissolve yeast in warm water. Stir in honey; let stand for 5 minutes. Add 3/4 cup all- purpose flour, whole wheat flour, oil, minced sage and salt. Beat on medium speed for 3 minutes or until smooth. Stir in enough remaining flour to form a soft dough (dough will be sticky).
Turn onto a lightly floured surface; knead until smooth and elastic, 6-8 minutes. Place in a greased bowl, turning once to grease the top. Cover and let rise in a warm place until doubled, about 1 hour.
Punch dough down. Cover and let rest for 5 minutes. Place 1 tablespoon olive oil in a 10-in. cast-iron or other ovenproof skillet; tilt pan to evenly coat. Add dough; shape to fit pan. Cover and let rise until doubled, about 30 minutes.
With fingertips, make several dimples over top of dough. For topping, brush dough with 1 teaspoon oil. Top with sage leaves; brush leaves with remaining oil. Sprinkle with cheese. Bake at 400° until golden brown, 10-15 minutes. Remove to a wire rack. Serve warm.
