Wash pork thoroughly.
Put in a pot then fill the pot with water (¾ full).
Set to boil over high heat/fire.
Just before it boils, skim the scum that will float on top if there's any (this is important, you don't want your broth with floating with scum).
Lower heat to medium to bring pot to simmer.
Season with fish sauce and ground black pepper.
Simmer for an hour or more or until pork is tender.
Add the potatoes and saba banana.
Cook for about 10 minutes or until potatoes and saba are al dente.
Add the cabbage and dried parsley flakes and cook for about 5 minutes or to your desired doneness of veggies.
Taste and adjust seasoning to your liking.
Serve with rice. Enjoy!
