Preheat oven to 350 degrees. Lightly mist a 9 x 13 baking dish with cooking spray and set aside.

In a large pot over medium heat, cook the turkey, mushrooms, celery, onion, fennel seed, cayenne and nutmeg until the turkey is broken up and cooked through and the vegetables have softened. Add the garlic and cook for an additional minute. Drain if necessary.

Pour the turkey mixture into a very large bowl and add the bread, apple, sage, salt, poultry seasoning and pepper. In a separate medium sized bowl, whisk together the eggs and chicken broth. Pour over the bread mixture in the large bowl and stir to coat and combine.

Pour the combined stuffing mixture from the bowl into the prepared baking dish. Sprinkle chopped pecans evenly across the top and bake uncovered for 30-35 minutes until top is browned.
