Step 1

In a large pot over medium heat, place pork, sinigang mix, onions, and enough water to cover the meat about 1-inch high. Bring to a boil, lower heat to a simmer, then cook until pork is tender, about 1 hour. (Alternatively, cook in a pressure cooker for 30 minutes.)

Step 2

When pork is almost tender, add labanos and then tomatoes. Cook until tender. Stir in miso paste and tender stems of kangkong. Bring back to a simmer, about 1 minute.

Step 3

When ready to serve, stir in kangkong leaves and let cook until just wilted. Remove pot from the heat, and serve hot with steamed white rice.
