Arrange mushrooms on a parchment lined baking sheet.
In a small dish toss together the bread crumbs and parmesan
Drizzle top of mushrooms with oil and heavily sprinkle on the crumb mixture into a thick layer. Sprinkle over some salt and pepper and bake at 425°F for 10 minutes until tops are golden.
For dressing, whisk together the vinegar, honey and salt. Then slowly drizzle in the oil while continually whisking. Season with pepper to taste.
To serve, divide arugula between 4-6 bowls, top with hot mushrooms right out of the oven, then drizzle with the dressing. Sprinkle with fresh shaved parmesan or crumbled goat cheese if desired.
