Add the meat in a pot (better if you use kerahi) with garlic & ginger and leave on medium heat for the water to dry.

When that is done add 3 glasses of water, cover and leave to tenderize. When the meat has softened add everything, including Cooking oil, except green chillies & tomatoes.

Increase the heat to dry water if any then add green chillies & tomatoes. Lower the heat and cook it covered for 5-10 minutes.

When the tomatoes are softened, increase the heat and cook till the water dries.
