Cut parchment paper to about 15 x 9 1/2 inches to form a sling to allow you to easily insert and remove the meatloaf from your slow cooker.

In a large mixing bowl combine turkey, egg yolks, oats, spinach, tomato paste, Italian seasoning, salt, and pepper.

Form into rectangle and place on parchment in slow cooker. Place sliced fennel all around the sides of the meatloaf. Mix the rest of the tomato paste with 1 teaspoon Italian seasoning, 2 teaspoons olive oil, and garlic. Coat the turkey with tomato sauce.

Cook on high 3-4 hours or low 6-7 hours.
