How to Make It
Gently wash and dry mushrooms. Trim the very bottom ends of mushrooms, leaving stems intact. Cut mushrooms vertically into very thin slices; arrange on a platter so they overlap slightly. Combine parsley, rind, and garlic in a bowl. Combine juice, salt, and pepper in a bowl. Gradually add oil to juice mixture, stirring constantly with a whisk. Drizzle juice mixture evenly over mushrooms; sprinkle with parsley mixture and cheese. Let stand at room temperature for at least 15 minutes before serving.
