Preheat oven to 375*. Grease an 8x1 1/2 or 9x 1 1/2 inch round baking pan; set aside. Unroll dough (do not separate); press preforations to seal. Brush dough with melted butter. In a small bowl, stir together the granulated sugar & cinnamon; sprinkle over dough. Starting from a long side, roll up dough. Using a sharp knife, slice dough into eight 1 1/2 inch pieces. Arrange pieces, cut side up, in prepared pan, flattening each slightly.
Bake for 15 to 18 minutes or until golden. Remove and cool rolls slightly in pan on a wire rack. Remove from pan. In a small bowl, stir together powdered sugar, vanilla & enough orange juice to make an icing of drizzling consistency. Drizzle over warm rolls. Serve warm.
