Bring a large pot of salted water to a boil and cook the pappardelle pasta until al dente, then drain and set aside.
While the pasta cooks, heat the olive oil in a large skillet over medium heat.
Add the finely diced onion, carrot, and celery to the skillet and sauté for 5 minutes until the vegetables are softened and translucent.
Add the ground turkey to the skillet, breaking it into small crumbles with a wooden spoon, and cook until browned and no longer pink.
Stir in the minced garlic, dried oregano, sea salt, and black pepper, cooking for one minute until the aromatics are fragrant.
Pour in the tomato puree and reduce the heat to low, allowing the sauce to simmer and thicken for approximately 10 minutes.
Add the cooked pappardelle ribbons directly into the skillet and toss thoroughly until every strand is coated in the turkey bolognese.
Plate the pasta and finish with a sprinkle of parmesan cheese before serving.
