Step 1

Prepare a grill for high heat. Whisk mirin, miso, vinegar, and ginger in a small bowl. Place asparagus in a pie plate or small baking dish and pour miso mixture over. Toss to coat.

Step 2

Grill asparagus, turning occasionally, until charred on all sides and crisp-tender, 4–5 minutes. Transfer to a platter. Squeeze lime juice over, then top with scallions and sesame seeds.
