Preheat your oven to 375°F and lightly grease a small oven-safe baking dish.
Bring a pot of salted water to a boil and cook the whole wheat ziti until al dente, then drain and set aside.
In a medium skillet, heat the olive oil over medium-high heat and sauté the minced garlic until fragrant.
Add the ground turkey to the skillet, seasoning with sea salt, black pepper, and dried oregano.
Cook the turkey until browned and fully cooked through, breaking it into small crumbles with a spatula.
Stir in the fresh spinach and tomato puree, simmering for 2 minutes until the spinach is wilted and the sauce is hot.
Combine the cooked ziti with the turkey and sauce mixture, then transfer everything to the prepared baking dish.
Dollop the ricotta cheese over the top and sprinkle evenly with the shredded mozzarella.
Bake for 15 minutes until the cheese is melted and the sauce is bubbly.
Remove from the oven and garnish with fresh basil chiffonade before serving.
