Because asparagus spears don't really have "sides," simply roll them around with tongs while grilling to guarantee even cooking.
1 tablespoon olive oil, divided
1 tablespoon chopped fresh flat-leaf parsley
1/2 teaspoon grated fresh lemon rind
2 teaspoons fresh lemon juice
1/2 teaspoon minced garlic
1 pound asparagus, trimmed
1/4 teaspoon salt
1/8 teaspoon black pepper
How to Make It
Combine 2 teaspoons olive oil and next 4 ingredients in a small bowl; stir well with a whisk, and set aside.
Drizzle remaining 1 teaspoon olive oil over asparagus. Place asparagus on grill rack coated with cooking spray; grill 6 minutes or until crisp-tender. Place asparagus on a serving platter, and sprinkle evenly with salt and pepper. Drizzle lemon-parsley mixture over asparagus.
