Preheat oven to 400°F and line a baking sheet with parchment paper.
Arrange eggplant rounds on the sheet, brush with olive oil, and season with sea salt and black pepper.
Roast eggplant for 15-20 minutes until tender and slightly golden.
While eggplant roasts, brown the ground turkey in a skillet over medium heat until cooked through.
Stir in the tomato puree, minced garlic, and dried oregano, then simmer for 5 minutes.
Create stacks by layering roasted eggplant, turkey sauce, and shredded mozzarella on the baking sheet.
Top with grated parmesan and bake for another 5-7 minutes until the cheese is melted and bubbly.
Garnish with fresh basil chiffonade before serving.
