Crisp Asian pears meet juicy fennel and peppery watercress in a refreshing salad that's a great start to any meal. For color we've added strips of tomato and pistachio nuts. A simple dressing of fresh lime juice and decadently delicious pistachio oil is light and fresh, balancing the sweetness of the pears and fennel perfectly.
Combine the lime juice and pistachio oil in a small glass jar. Season with salt and pepper to taste. Shake vigorously to combine. Set aside at room temperature. The dressing can be made up to 2 days in advance, and stored in the refrigerator. Let it come to room temperature before using for maximum flavor.
Combine the pear and fennel in a small bowl and toss with one tablespoon of the dressing.
Place the watercress in a large bowl. Add the pear-fennel mixture and tomatoes, and toss to combine. Drizzle with half of the remaining dressing, tossing to coat. Add more dressing, if needed, to taste. Transfer the salad to a large platter or divide among 4 salad plates. Sprinkle with pistachio nuts and serve immediately.
