This recipe is from my 1980's Better Homes and Gardens Low-Cost Cooking Cookbook, but I did modify the recipe to my liking. I love these scotch meat loaves with the ketchup glaze on top. You can make these meat loaves with either ground beef or with ground pork sausage. My husband and I especially enjoy them made with "seasoned" ground pork sausage, which already has salt, ground black pepper, minced garlic, and ground sage added to it.
In a mixing bowl, combine the beaten egg, bread crumbs, diced onion, diced green pepper, plus the salt and pepper.
Add the ground beef or ground pork; mix well.
Shape equal portions of the meat mixture around each hard boiled egg; completely enclosing the egg.
Arrange the meat loaves in a 13x9x2-inch baking dish. (If I'm using 90% lean ground beef, I'll lightly grease the baking dish before adding the meat loaves.)
Bake in a 350º oven for 30 minutes.
While the meat loaves are baking in the oven, prepare the sauce.
In a bowl, combine all of the sauce ingredients.
Once the meat loaves have baked for 30 minutes, remove the baking dish from the oven, and discard any excess fat.
Pour the sauce over the meat loaves, and return the baking dish to the oven.
Continue baking the meat loaves in the oven for 15 minutes.
Once the meat loaves are done baking, remove from baking dish and serve immediately.
*Note: Sometimes when I'm mixing up the meat loaves, I'll substitute 1/4 cup to 1/3 cup of plain dried bread crumbs for the soft bread crumbs. I have also made the meat loaves using either 85% or 87% ground beef. Also, if desired, you can opt to make 4 meat loaves, by just using 4 large size hard boiled eggs, and shaping a 1/4 of the meat mixture around each hard boiled egg. Arrange the meat loaves in an 8 or 9-inch baking pan, and bake as stated in cooking instructions. Also, I did want to mention, when it comes to preparing the medium hard boiled eggs, I let the eggs come to a boil in a saucepan of water, I then remove the pan from the heat, cover the pan, and let the eggs sit for 9 minutes. Afterwards, I place the eggs in cold water (which I also added ice cubes to it), and let the eggs sit for 15 minutes. I then remove the eggs, peel them, rinse them under cold water, and pat them dry with paper toweling before I proceed to make the meatloaves.
