Heat oven to 325°F. Lightly grease baking sheet. Separate dough into 8 triangles. For each roll, place 2 triangles together, one on top of the other; press all edges together to seal. Roll up, starting at shortest side of triangle and rolling to opposite point. Place point side down on greased baking sheet. Brush each roll with egg white. Sprinkle evenly with 2 teaspoons sugar.
