Heat oven to 350°. Unroll crescent dough sheet onto large cutting board. Sprinkle the dough with the mozzarella cheese, Parmesan cheese, salami and herbs. Starting at shortest side, roll up the dough sheet into one large cylinder; pinch edge to seal. Cut roll into 12 slices. Place slices, cut side down, 1 inch apart on ungreased cookie sheet. Gently press down on slices to ensure uniform baking. Brush with beaten egg white. Bake 18 to 20 minutes or until golden brown.
