Directions

Either light a medium fire in grill or preheat broiler. Whisk garlic, ginger, rice wine vinegar, soy sauce, and sesame oil, along with salt and pepper to taste, in medium bowl. Brush asparagus with about 1 tablespoon dressing to coat lightly.
2. Either grill asparagus, turning halfway through cooking time, until tender and streaked with light grill marks, 5 to 7 minutes, or line up spears in single layer on heavy jellyroll or rimmed baking sheet and broil, placing sheet about 4 inches from top heating element and shaking it once halfway through cooking to rotate spears, until tender and browned in some spots, 6 to 8 minutes.
3. Whisk peanut butter, cilantro, and 1 tablespoon water into remaining dressing; toss with asparagus. Transfer to serving platter, adjust seasoning with salt and pepper, sprinkle with minced scallion, and serve immediately.
