Prepare the seasoned ground meat: Combine the ground pork (or your choice), oyster sauce, Maggi Seasoning, and garlic (if using) in a bowl. Mix thoroughly.

Add a little water to a sauté pan and bring it to a boil. Add the meat mixture and cook on medium heat, stirring constantly to break up any lumps until fully cooked (about 5-7 minutes). Remove from heat and stir in chopped green onions.

Slice your Chinese sausages and Vietnamese ham thinly. In another greased pan over medium heat, sear these slices just until they are browned (2-3 minutes) and set aside.

Heat your cast-iron pan (or oven-proof dish) over medium-low heat. Add the butter; let it melt and watch for bubbling.

Carefully crack the eggs into the pan. Layer on the cooked sausages, Vietnamese ham, and seasoned ground meat, ensuring even distribution.

Cover the pan with a lid or a large plate to trap steam and help eggs cook evenly. Cook until the whites are set and yolks are as desired (about 5-8 minutes). Remove from heat and garnish with extra green onions and a sprinkle of pepper.

Serve with your favorite bread and condiments like Sriracha or ketchup. Enjoy!
