Combine 2 cups flour, cheese, parsley, undissolved yeast, salt, sugar and herbs in a large bowl. Gradually add water and olive oil. Beat 2 minutes at medium speed of electric mixer, scraping bowl occasionally. Stir in enough remaining flour to make a soft dough. Knead on lightly floured surface until smooth and elastic, about 8 to 10 minutes. Cover; let rest 10 minutes.
Divide dough in half; shape each into 5-inch smooth ball. Place on 2 greased baking sheets. Cover; let rise in warm, draft-free place until doubled in size, about 30 to 45 minutes.
Brush with egg white; sprinkle with sesame seed. Bake at 375°F for 25 to 30 minutes or until done. Remove from sheets; cool on wire racks.
