Preheat oven to 350 degrees F.
Combine the sugar and soy sauce in a small bowl, stir until sugar dissolves, and set aside.
In a large bowl, combine the pork, beef and vegetables. Add the beaten eggs, the soy and sugar, and the black pepper to the meat mixture and stir until everything is well-combined (mixing with your hands is best for this).
Evenly divide the meat mixture between two sheets of aluminum foil about 15-inches long. Spread the meat into a rectangle (about 10×6 inches) in the middle of the foil, and then place filling (hard boiled eggs, hot dogs and/or Vienna Sausages) in the center of the meat:
Using the foil, tightly roll the meat over the filling and into a log shape. Twist the ends of the foil closed, ensuring the meat is tightly packed.
Place the rolled meat onto a cookie sheet (it may be helpful to line the cookie sheet with more foil, as the meat will leak fat and juices), then place in the oven for 1 hour to 1hour 15 minutes. You can also check for doneness (160 degrees F. is good) by sticking an instant-read thermometer through the foil and into the meat–just make sure the thermometer is stuck in all meat rather than in an egg or sausage, otherwise you’ll get a false reading.
Allow the meat to cool in the foil before unwrapping. Once meat is cool, unrwrap and slice. Serve with white rice, or enjoy leftovers in some Pan de sal for a Pinoy Meatloaf Sandwich.
