Preheat your oven to 375°F (190°C).
Cook the whole grain lasagna noodles in a pot of boiling water until al dente, then drain and set aside.
Heat the olive oil in a large skillet over medium heat and brown the ground turkey until no longer pink.
Season the turkey with the sea salt, black pepper, garlic powder, and dried oregano.
Add the fresh baby spinach to the skillet and stir for 1 minute until the leaves are just wilted.
In a small mixing bowl, combine the ricotta cheese with half of the grated parmesan cheese.
Spread two tablespoons of tomato puree on the bottom of a small individual-sized baking dish.
Place half of a lasagna noodle over the sauce, followed by a layer of the turkey and spinach mixture and a dollop of the ricotta blend.
Repeat the layers of noodle, meat, and cheese until all ingredients are used, finishing with a final spread of tomato puree and the remaining parmesan.
Bake for 20 minutes until the sauce is bubbling and the cheese topping has turned a beautiful golden brown.
