Preheat the oven to 425°F (220°C) and line a baking tray with parchment paper.
In a large bowl, toss the zucchini slices with olive oil, The Holly Tree Organic Italian Seasoning, The Holly Tree Organic Oregano, The Holly Tree Organic Basil, The Holly Tree Organic Black Pepper Powder, and Salt until evenly coated.
Arrange the zucchini slices in a single layer on the prepared baking tray.
Sprinkle the grated Parmesan evenly over the zucchini.
Bake for 18–22 minutes, or until the zucchini is tender and the edges are lightly golden.
For a crispier finish, broil for an additional 1–2 minutes.
Transfer to a serving platter and garnish with chopped fresh parsley.
Finish with a light sprinkle of The Holly Tree Organic Italian Seasoning before serving.
