Chicory and Endive Salad with Spiced Pistachios

Preheat the oven to 375°. In a shallow dish, mix the hazelnut oil with the sherry vinegar. Add the radicchio and let marinate for 10 minutes, turning often.

Scatter the pistachios on a rimmed baking sheet and sprinkle with a pinch each of salt, sugar, cumin and cayenne. Bake until toasted, about 5 minutes.

Light a grill. Season the radicchio with salt and pepper and grill over high heat until lightly charred on 2 sides, about 2 minutes per side. Transfer to a work surface and let cool slightly. Cut the radicchio into bite-size pieces.

In a large skillet, heat the olive oil. Add the shallot and cook over moderate heat until softened, about 4 minutes. Add the balsamic vinegar and bring to a boil over moderate heat. Add the chicory and cook, stirring occasionally, until just tender, about 5 minutes. Add the radicchio, red and yellow endives and chopped tarragon and toss well. Season with salt and pepper. Mound the salad on plates, garnish with the spiced pistachios and serve.
