In a bowl, combine the beef and pork, add the sausage, tomato puree, ketchup, salt, corn flakes, and all other ingredients. Mix everything very well.

In a baking dish, lay down a layer of bacon, pour in the meat mixture, place some bacon on top, and cover with aluminum foil.

Preheat the oven and bake at 350°F (180°C) for 45 minutes. Uncover to brown the surface and finish cooking for about 30 more minutes.
