Preheat the oven to 350 degrees F.
In a large bowl, beat the eggs. Add milk, bread crumbs, and oatmeal. Stir in carrots, onions, cheese, and seasonings. Add beef and sausage and mix well. In a shallow baking dish, shape beef mixture into the shape you want or bake in a bread pan. Bake for 45 minutes, until meat is cooked through.
While baking combine topping ingredients.
After 45 minutes, spoon half of the topping over the meatloaf. Return to the oven and continue baking for an additional 30 minutes. Remove from oven and let stand for 10 minutes.
Pour remaining sauce on top of meatloaf if desired.
