                Thin ribbons of Parmigiano-Reggiano carry the mushrooms’ meaty robustness through each bite of greens. It might look like a lot of mushrooms when you’re putting the salad together, but it allows everyone to have a generous helping.

                                            Heat lightly oiled grill pan over moderately high heat until hot but not smoking, then grill mushrooms in 3 batches, turning frequently, until golden brown, about 5 minutes per batch. Transfer as grilled to a cutting board and cool to room temperature.

                                            Cut portabellas into 1/2-inch-wide wedges, then halve shiitake and cremini mushrooms and cut chanterelles (if large) lengthwise into 1/2-inch pieces.

                                            Transfer mushrooms to reserved vinaigrette, tossing to coat, then add arugula, cheese, and salt and pepper to taste and toss again. 
 
                        
                    
                    Cooks’ notes: - Mushrooms (marinated but without additional vinaigrette) can be grilled and cut 4 hours ahead and cooled, uncovered, then kept, loosely covered, at room temperature. Pour off any juices before adding to vinaigrette.
- Vinaigrette keeps, covered and chilled, 1 day.
- Cheese can be shaved 1 day ahead and chilled in a sealed plastic bag.
