Saute chopped onion in bacon grease over medium heat until glossy and transparent,
Soak the bread in enough water to thoroughly wet it and make it soggy and waterlogged. Then squeeze out the excess water and set aside.
In a large bowl set the meat, Maggi sauce, eggs, cooked onion, and soaked bread crumbs.
Pour all the dry meat filling ingredients over the meat and mix by hand like a meatloaf.
