Ingredients
3/4 cup walnut halves or pieces
8 ounces Brussels sprouts, trimmed and thinly sliced lengthwise (1 1/2 cups)
1 small head radicchio (8 ounces), cored and thinly sliced (1 1/2cups)
Kosher salt (we use Diamond Crystal) and freshly ground pepper
3 endives, trimmed and thinly sliced lengthwise (2 cups)
1 tablespoon white-wine vinegar
1 tablespoon fresh lemon juice
1/4 cup extra-virgin olive oil
3 oranges, peels and pith removed, cut into supremes
Preparation
Preheat oven to 350°F. Spread walnuts on a rimmed baking sheet in a single layer. Toast until slightly darkened and fragrant, 12 to 14 minutes. Let cool completely.
In a large bowl, toss Brussels sprouts and radicchio with 1 teaspoon salt. Rub mixture between your palms until greens soften slightly and turn shiny. Toss in endives. In a small bowl, whisk together vinegar, lemon juice, and oil; season generously with salt and pepper. Pour dressing over greens, tossing to evenly coat. Top with walnuts and orange supremes; serve.
