Heat oven to 375°F. Separate dough into 8 triangles. Sprinkle each with scant 1 teaspoon Parmesan cheese. Roll up each, starting at shortest side of triangle and rolling to opposite point.
Place rolls, point side down, on ungreased cookie sheets; curve each into crescent shape. Brush each with beaten egg; sprinkle with remaining Parmesan cheese.
Bake at 375°F. for 10 to 12 minutes or until golden brown. Serve warm.
