Cook your noodles in a large pot of boiling water for 8-10 minutes until cooked through.

Set a large saucepan or skillet over medium heat and add the olive oil and butter. When the butter has melted, add the onion and celery and cook for 3 to 4 minutes, stirring occasionally, until softened.

Add the flour and cook for around 1 minute, stirring frequently until lightly browned. While whisking, add the broth and milk and bring to a simmer. Add the salt, pepper, and poultry seasoning, then cook until thickened enough to coat a spoon.

Stir in the turkey and vegetables and cook for another minute.

Stir in the cooked noodles and transfer the mixture to a 9 by 13 baking dish.

Top with shredded cheese then bake uncovered for 15 to 20 minutes until the cheese is melted and the sauce is bubbling. Let cool for 5 minutes, then serve.
