Preheat oven to 375F.
Melt ghee/butter in a pan over medium heat, then add celery and onions and stir-fry for 5 minutes or until softened. Add walnuts and sauté for another 2 minutes.
While the onion mixture cools, add the ground turkey, eggs, flaxseed meal/almond flour, herbs and spices to a bowl and mix well. Then add the cooked onion mixture and mix well.
Transfer the mixture to a 9x5 loaf pan and bake at 375F for 45 minutes.
While the meatloaf is baking, combine ketchup and cranberry sauce together in a bowl and mix well.
Remove the meatloaf, spread the ketchup on top, then bake for another 5 minutes or until cooked through (should reach an internal temp of 165F).
Allow the loaf to rest for 10 minutes, then slice and serve.
