Preheat oven to 400 degrees F (200 degrees C).
Line two baking sheets with foil, and spray with Nonstick Cooking Spray (to taste).
Place 1/4 thick slices of Zucchini (1 pound) in a plastic bag with Olive Oil (1 tablespoon) and shake to coat evenly.
In a wide bowl or plate, combine Panko Breadcrumbs (1/4 cup), Parmesan Cheese (1/4 cup), Kosher Salt (1/4 teaspoon), and Ground Black Pepper (to taste).
Place zucchini rounds in the bread crumb mixture, coating both sides, and pressing the mixture onto the rounds.
Place rounds in a single layer on the baking sheet, and sprinkle with remaining bread crumb mixture.
Bake 22-27 minutes, until golden brown.
