Heat oven to 375°F. Separate dough into 8 triangles; press each slightly to enlarge. Spread 1 tablespoon hazelnut spread evenly over each triangle. Sprinkle each with 1 tablespoon toffee bits and 1 tablespoon pecans; press in lightly.
Roll up, starting with shortest side of triangle and rolling to opposite point. Place point side down on ungreased cookie sheet; curve into crescent shape.
Bake 12 to 17 minutes or until deep golden brown. Remove from cookie sheet; cool 5 minutes. If desired, decorate top of each roll with additional hazelnut spread.
