Preheat oven to 350 degrees F and line a baking sheet with parchment paper. Set aside.
Add the onion to a food processor and pulse until finely chopped. Then, add the avocado oil or butter to a small skillet over medium heat. Once warm, add the finely chopped onion and minced garlic. Saute a few minutes or until softened. Remove from heat and set aside to cool slightly.
To a large bowl, add the ground turkey, egg, pumpkin puree, coconut flour, coconut sugar, pumpkin pie spice, cumin, turmeric, sea salt and black pepper. Lastly, add the slightly cooled onion mixture. Mix well with your hands, but be careful not to overmix.
Place meat mixture onto prepared baking sheet and shape into an even loaf with your hands. Try to keep it level, so it cooks evenly.
Bake in preheated oven for 60-65 minutes or until meat thermometer reads 160 degrees F. Once done, let sit 10 mintues before slicing.
