Instructions

1. Preheat the oven to 350 degrees F.
2. Line 2 heavy large baking sheets with parchment paper.
3. Roughly chop rosemary. In a small bowl, combine chopped rosemary and olive oil.
4. Unroll the puff pastry sheet out onto a lightly floured cutting board and roll out into a rectangle approximately 1/8" thick. Using a knife or a pizza cutter, cut the dough into 1-1/2" wide strips. 
5. Using a pastry brush, brush the olive oil and rosemary mixture over the cut strips.
6. Separate and twist each strip and transfer to the baking sheet. Repeat with the second sheet of pastry.
7. Sprinkle with kosher salt. Bake for 10-15 minutes, until the breadsticks are golden brown. Transfer the breadsticks from the baking sheet to a basket and serve warm.
