Combine feta and next 7 ingredients (feta through egg white) in a bowl.

Roll dough into a 16" x 10" rectangle on a lightly floured surface. Spread spinach mixture over dough, leaving a 1/2" border. Beginning with a long side, roll up jelly-roll fashion; pinch seam and ends to seal. Place roll, seam side down, on a baking sheet coated with cooking spray. Cut diagonal slits into top of the roll using a sharp knife. Cover and let rise in a warn place (85°), 1 hour or until doubled in size.

Preheat oven to 350°.

Sprinkle Parmesan cheese over the top of the roll. Bake at 350° for 45 minutes or until golden.
