In a large skillet over medium heat, add the first 6 ingredients (beef through salt and pepper). Cook for 5 to 10 minutes, until beef is brown. To the skillet, add the next 5 ingredients (beef broth through cauliflower) and cook for 5 minutes, until vegetables are slightly tender.
Into a large baking dish, pour the beef and vegetable mixture. Top with mashed sweet potatoes, and then drizzle over the melted ghee. Cover with aluminum foil.
Bake for 20 minutes, then remove foil and bake for 15 minutes until potatoes are brown on the edges and the inside is bubbling.
Serve warm.
