Ingredients

1 pound jumbo asparagus, tough ends discarded 

1/2 teaspoon Dijon mustard 

1 1/2 tablespoons white-wine vinegar 

3 tablespoons extra-virgin olive oil 

1/4 teaspoon lemon zest 

Pinch of sugar 

Coarse salt and freshly ground pepper 

Preparation

Preheat a grill pan over high heat. Peel lower two thirds of each asparagus stalk with a vegetable peeler.

In a small bowl, whisk together mustard, vinegar, olive oil, lemon zest, sugar, salt and pepper. Place asparagus in a shallow dish and pour over vinaigrette; toss to coat.

Place asparagus on grill pan, reserving any juices that have accumulated in the dish. Cook until tender and grill marks appear, 5 to 7 minutes. Transfer asparagus to a serving platter; drizzle with reserved juices.
