Boil pork belly in water until it becomes tender. Separate the meat and broth when ready to cook.
Heat oil in a deep pan or a pot and fry the potatoes, carrots, and bananas until the edges are slightly browned. Remove from oil and transfer to a plate.
In the same oil saute garlic, onion, and tomato until limp.
Add the pork belly cuts and the tomato paste. Season with fish sauce and ground pepper.
Next, add back the fried potatoes, carrots and banana plantain (saba) and also the chickpeas.
Pour in the broth/water and let it simmer to cook the potatoes and carrots and until the broth turns into a thicker sauce.
Lastly, add the pak choi and turn off the heat. Cover the pot for 3 minutes to cook the pak choi.
Serve hot with rice.
Notes
If the plantain bananas are not sweet enough, add a teaspoon of sugar.
