Use grating disc of a food processor or a hand grater to shred carrots. Place them in a medium bowl. Stir in orange juice, olive oil, garlic and pepper flakes. Heat a small, dry skillet on medium and add pine nuts. Cook, shaking pan constantly, until they are fragrant and lightly browned - about 5 minutes. Add toasted nuts to carrots and toss. Add herbs, toss and season to taste with coarse salt. Serve immediately.
