Parmesan-crusted asparagus

1 lb asparagus (about 40 thin spears)
1 T olive oil
1 oz parmesan cheese curls
Fresh ground pepper
Balsamic vinegar

Preheat oven to 450 degrees F. Place asparagus in a single layer on a nonstick baking sheet. Drizzle with oil and toss well. Spread the parmesan over the top of the asparagus.

Bake in top of the oven until cheese is melted and asparagus is barely tender, 12-15 minutes. Season with pepper to taste. Sprinkle with balsamic vinegar and serve hot.
