Preheat your oven to 400°F (200°C).
In a large skillet over medium-high heat, add 0.5 tbsp of olive oil and the ground turkey.
Season the turkey with the garlic powder, half of the sea salt, and half of the black pepper, cooking until browned and fully cooked through.
While the turkey cooks, slice the zucchini and Roma tomatoes into 1/4-inch thick rounds.
Transfer the cooked ground turkey into the bottom of a small baking dish, spreading it into an even layer.
Arrange the zucchini and tomato slices in an alternating, overlapping pattern on top of the turkey base.
Drizzle the remaining 0.5 tbsp of olive oil over the vegetables and sprinkle with the dried oregano, remaining salt, remaining pepper, and the parmesan cheese.
Bake for 20-25 minutes until the zucchini is tender and the cheese has formed a bubbly, golden crust.
Remove from the oven and garnish with freshly chopped parsley before serving.
