-  Preheat oven to 350°. 
-  If using milk and bread, pour milk over bread slices and let soak for several minutes. 
-  Place ground beef, milk-soaked bread (or bread crumbs), Parmesan cheese, both salts, pepper, and parsley in a large mixing bowl. 
-  Pour in beaten eggs. 
-  With clean hands, mix the ingredients until well combined. 
-  Form the mixture into loaf shape on a broiler pan, which will allow the fat to drain. Line the bottom of the pan with foil to make clean up easier. I put the meatloaf on a wire rack above a foil-lined cookie sheet which worked well (didn't have a broiler pan). 
-  Lay bacon slices over the top, tucking them underneath the meatloaf. I overlapped my slices by 25-50%. 
-  Make the sauce (mix all ingredients listed above together) and pour 1/3 of the mixture over the top of the bacon. Spread evenly over the whole meatloaf. 
-  Bake for 45 minutes, then pour another 1/3 of the sauce over the top. 
-  Bake for another 15 minutes. Slice and serve with the remaining sauce.
