The flavors of autumn shine in this simple but elegant salad. Hazelnut oil is a lovely base for a vinaigrette and is worth seeking out in a specialty market.
Combine the dressing ingredients in a glass jar and shake vigorously to combine.
Pour the dressing in a large bowl. Add the greens and hazelnuts. Toss to coat.
Divide between chilled plates and garnish each serving with the figs and Gruyère.
