While the potatoes are cooking, let’s make the sauce! Heat the ghee or coconut oil in a medium sized pan over medium-low heat. Add the diced onion and sauté until tender, about 5 minutes. Then, add the beef to the pan and sauté until cooked through. Drain the fat if needed/desired. Next, add the garlic and sauté until it becomes fragrant, about 30 seconds. Add the chili powder, cumin and salt to the pan and stir it like you mean it! Finally, add the tomato sauce to the pan and stir again like you mean it! Simmer for 10 minutes, stirring occasionally.
