Preheat oven to 350 degrees F Grease small loaf pan with some ghee. In a large bowl, lightly beat the eggs. Add the sausage, onion, and half the cream cheese. Mix thoroughly. Pour the meatloaf and egg mixture into the loaf pan. Add to the oven and bake, uncovered, about 30 minutes or until stiff. Remove from oven and let sit for 5 minutes. Some fat may have risen to the top and begun to cool. You can use a spoon to lightly scrape it off (it should come right off without ruining the meatloaf top.) Spread the remaining cream cheese over the top of the meatloaf, then top it with cheddar cheese and scallions. Add the meatloaf back to the oven. Bake for about 5 more minutes, then switch to Broil for about 2-3 or until the cheddar cheese begins to golden and crisp. Remove from oven, and let the meatloaf sit for at least 5 minutes before slicing and serving.
