Clean the liver and set to drain.
Heat oil in a saucepan. Add in the onions and green chillies with a pinch of salt and saute till soft.
Add in the ginger garlic paste and the tomato paste and saute for around five minutes till the raw smell of the paste goes.
Now add in the masala powders and saute for at least 10 minutes, till the masala turn into a dark color.
Add in 1/2 cup of water (not more, as the liver will release water), the drained liver pieces and salt and cook with a closed lid on low to medium flame till the liver is soft and well cooked.
Garnish with curry leaves or coriander leaves and serve warm with chappathis!
