Balsamic & Parmesan Broccoli

Heat 1 tablespoon oil in a large flat-bottom carbon-steel wok over medium-high heat. Add broccoli and cook, stirring, until browned in spots, about 4 minutes. Reduce heat to medium. Push the broccoli to the sides and add the remaining 1 tablespoon oil, shallot, garlic, vinegar, salt and pepper; cook, stirring often, until the broccoli is tender, about 3 minutes more. Remove from heat and sprinkle with Parmesan. Cover and let stand until the cheese is melted, 1 to 2 minutes.
