Sprinkle half the pecans in a greased 10" fluted tube pan. Drizzle with a third of the caramel mixture. Open the tubes of breadstick dough (do not unroll). Cut each into eight slices; dip in butter, then roll in cinnamon-sugar. Place half in the pan; sprinkle with remaining pecans. Drizzle with half of the caramel mixture. Top with remaining dough. Drizzle with remaining caramel mixture.
