Preheat oven to 350°.

Using a very sharp knife and starting at the tip end cut very thin slices (1/8" if you can do it) from the tip to almost the stem. Do not cut through stem end of zucchini.

Spray foil lined pan or pan with cooking spray. Arrange the zucchini on the baking sheets and carefully spread apart the slices to fan out on sheet. Drizzle each fanned zucchini with some olive oil. Sprinkle with salt and pepper, and then some of the rosemary, Parmesan, Panko crumbs and pistachio nuts.

Bake in 350° oven until the topping has browned nicely, about 10-15 minutes. You don't want to overcook because they will become too limp. Carefully put one fanned zucchini on each dinner plate and serve.

Bon Appetite!
