Preheat oven to 375 F.
In a medium skillet, add 1 tbsp olive oil and sauté the livers, add ½ tsp salt. Cook for about 8 minutes. Once cool, blend in a food processor or high speed blender, set aside.
In the same skillet sauté the onions in 2 Tbsp ghee. Once the onions are soft add carrots, spinach, garlic, and salt. Remove from heat.
In a large bowl, combine the beef, 1/3 cup of the ketchup, eggs, cassava flour, dried oregano, mustard powder, garlic powder, salt, and pepper.
Add liver and cooked onions, carrots, and spinach. Mix well with your hands.
Transfer the mixture into a loaf pan and bake for 25 minutes.
Take out and spread remaining ketchup on top. If it starts to brown too soon cover with aluminum foil. Bake for another 40 minutes until center reaches 160F.
Allow the meatloaf to rest 10 minutes before slicing. This will help it stay together.
