- Place an oven rack in the center of the oven. Preheat the oven to 375 degrees F. Spray a 9-by-5-inch loaf pan with cooking spray.
- In a large bowl, stir together the breadcrumbs, parsley, sun-dried tomatoes, garlic, if using, eggs, milk, feta, salt, and pepper. Add the turkey and gently stir to combine, being careful not to overwork the meat.
- Carefully pack the meat mixture into the prepared pan and bake until the internal temperature registers 165 degrees F on an instant-read thermometer, about 45 minutes. Remove from the oven and let rest for 5 minutes. Slice and serve.
