Step 1Heat the oven to 500 degrees. Combine the bread and milk in a large bowl and soak for 10 minutes. Add the turkey, eggs, cheese, pancetta, onion, garlic, 1 tablespoon ketchup, balsamic glaze, parsley, oregano, dried bread crumbs, salt and pepper to taste. Mix well with your hands.
Step 2Shape into an 8-inch by 5-inch loaf and transfer to a rimmed baking sheet. Bake for 15 minutes. Reduce the heat to 325 degrees and slather the remaining ketchup all over the top of the loaf. Bake until a meat thermometer inserted in the center of the loaf reads 165 degrees, about 45 minutes. Remove the meatloaf and set it aside to rest for 10 minutes, then transfer to a platter and serve.
