Place the raisins in a medium bowl and cover with warm water. Allow to soak at least 20 minutes, or until soft. Toss the greens, pears and carrots together in a large bowl. Sprinkle pine nuts and salt over the salad. Once the raisins have plumped, drain and gently squeeze to remove excess water. Add the raisins to the top of salad. Sprinkle the vinegar over the salad, then dress with extra virgin pine nut oil.
