Preheat oven to 375℉. In a shallow bowl, add slices of bread and pour milk over top. Allow the bread to soak for about 5 minutes.
4 slices white bread, 1 cup milk
While the bread is soaking, combine ground beef, ground sausage, garlic powder, Italian seasoning, Parmesan cheese, breadcrumbs, and 2 eggs in a large bowl. Mix well.
1 pound ground beef, 1 pound ground sausage, 2 eggs, ½ cup parmesan cheese, ½ teaspoon garlic powder, 1 cup regular breadcrumbs, 1 tablespoon dried basil, 1 tablespoon dried oregano, 1 tablespoon dried rosemary, 1 tablespoon dried parsley, 1 tablespoon dried thyme
Squeeze any remaining milk out of the bread and add the bread to the meat mixture. Mix well.
Spray a 9 by 5-inch loaf pan with cooking spray. Add the meat to the loaf pan and spread it evenly.
Create a hollow line in the middle of the meat mixture and add blocks of mozzarella cheese. Cover back up with meat. (Optional, but stuffed meatloaf is the best!)
½ block mozzarella cheese
Top with tomato sauce and shredded mozzarella cheese.
½ cup tomato sauce, ½ cup shredded mozzarella cheese
Bake, uncovered, for 40 minutes or until the cheese is golden and melted. Slice, serve, and enjoy!
