2 large heads endive (about 13 ounces), outer leaves reserved, remaining leaves sliced into 1/2-inch pieces
1 pear, cored and sliced 1/4 inch thick
1/2 cup toasted walnut halves
1/2 cup crumbled Roquefort cheese
In a small bowl, whisk together vinegar, salt, and pepper. Slowly whisk in oils; set aside. In a medium bowl, combine whole and cut-up endive, pear slices, walnuts, and cheese. Drizzle with dressing; gently toss to coat evenly. Divide among four salad bowls. Serve immediately.
