Preparation Preheat oven to 350°F. Whisk 1/2 cup oil and lemon juice in small bowl. Season dressing with salt and pepper. Heat 1 tablespoon oil in large skillet over medium heat.

Let cherries soak in bowl 15 minutes to soften. Drain. DO AHEAD: Dressing, prosciutto, grapes, and cherries can be made 2 hours ahead. Let stand at room temperature. Mix greens, matchstick-size pear pieces, dressing, 2/3 of prosciutto, grapes, and cherries in large bowl. Season with salt and pepper. Divide among plates. Garnish with pear slices, drizzle with vinegar, and sprinkle with pine nuts and remaining prosciutto. Garnish with cheese.
