Preheat the oven to 350 degrees.
Place the ground beef in a large bowl and break it up into smaller chunks. Pour the stuffing over top. Pour the milk and eggs over the stuffing, and sprinkle with salt. Using your hands, gently stir the meat together with the stuffing and liquid ingredients until it is well combined and adhering to itself.
Transfer the mixture to a baking dish and shape into a loaf about 2-2 ½ inches thick. Bake for 35 minutes.
While the meatloaf bakes, whisk together the ketchup, brown sugar, worcestershire, and dijon mustard in a small bowl.
Remove the meatloaf from the oven and add the glaze to the top. Bake another 15-20 minutes, or until the meatloaf reaches an internal temperature of 160 degrees. Remove from the oven, then allow to rest for 10 minutes before slicing and serving.
