In a large pot, bring the water to a boil. Add the pork belly (or other pork cuts), onion, and peppercorns. Let it simmer for about 45 minutes to 1 hour, or until the pork becomes tender. Skim off any scum or impurities that float to the surface.
Add Potatoes and Corn:
Once the pork is tender, add the quartered potatoes and corn (if using). Continue simmering for another 10-15 minutes, or until the potatoes are cooked through.
Season the Broth:
Add fish sauce and adjust the seasoning with salt, depending on your taste. Let the broth simmer for a few more minutes to absorb the flavors.
Add Vegetables:
Add the cabbage and saba bananas (if using). Simmer for about 5 minutes, or until the cabbage is tender but still crisp.
Finally, add the pechay or bok choy and simmer for another 2-3 minutes until the leaves are wilted.
Serve:
Once everything is cooked, remove from heat and transfer to a serving bowl. Garnish with green onions or leeks, if desired.
Serve hot with steamed rice and additional fish sauce or calamansi on the side for extra seasoning.
