Mix 2 tablespoons olive oil, 1 teaspoon each fennel seeds, poppy seeds and sesame seeds, and 1/2 teaspoon each salt and pepper. Roll out an 11-ounce package refrigerated breadstick dough into a 16-by-8-inch rectangle. Cut into twelve 16-inch strips and twist into breadsticks. Brush with the oil mixture. Place on 2 parchment-lined baking sheets and bake in a 400 degrees F oven until golden, about 12 minutes.
