Heat oil in a large pot or pressure cooker. Add the chopped onions and sauté until translucent.
Add the minced garlic and grated ginger, and cook for a couple of minutes until fragrant.
Add the pork pieces to the pot and brown them on all sides.
Sprinkle turmeric powder, cumin powder, coriander powder, and salt over the pork. Mix well to coat the meat with the spices.
Add the chopped tomatoes and sliced green chilies to the pot. Stir everything together.
Add water just enough to cover the pork pieces. Cover the pot with a lid and let it simmer for about 45-60 minutes, or until the pork is tender.
Once the pork is cooked, check for seasoning and adjust salt if needed.
Garnish with fresh coriander leaves before serving.
Serve the Meetei Classical Pork Curry hot with steamed rice or flatbread.
Enjoy!
