Make the meatballs by combining the ground pork, bread crumbs, egg, salt, and pepper in a bowl. Mix well.
Scoop about a tablespoon of the mixture and roll it into a ball shaped figure. Do this step until all the ground pork mixture is consumed.
Heat 4 tablespoons of cooking oil in a pan. Pan fry the meatballs in low to medium heat until the color of the outer part turns medium brown. Remove the fried meatballs and set aside.
Meanwhile, start to prepare the soup by pouring the remaining 2 tablespoons of cooking oil in a clean cooking pot.
Saute the onion and garlic. Once the onion becomes soft, put-in the cooked meatballs.
Pour-in the water. Let boil.
Add the beef broth and tomato sauce. Let boil and simmer for 10 minutes.
Pour-in the fish sauce then add the loofah and spring onions. Stir and cook for 3 minutes.
Put-in the misua noodles. Cook for 2 minutes (add more water if needed).
