Heat oven to 350℉.
Separate dough into 4 rectangles; firmly press perforations to seal.
Spoon ¼ of chopped green onions onto center of each rectangle; top with ¼ of cheese cubes. Top each with ¼ of chicken, pressing into cheese.
Fold short ends over chicken, overlapping slightly. Fold open ends over about ½ inch to form rectangle. Press all edges to seal.
Place seam side down on ungreased 15 x 10 x 1-inch baking pan or cookie sheet. Cut three 1-inch slashes on top of each roll to form steam vents. Brush with egg; sprinkle with rosemary and parmesan cheese.
Bake at 350℉ for 21-26 minutes or until golden brown.
Garnish each sandwich with 2 tomato wedges (if desired) and 1 green onion. Let stand 5 minutes before serving.
