Heat oil and fry finely chopped garlic and chilli for half a minute.
Add finely chopped onion and fry until transparent. After that, add the coriander leaves.
Once it reduces in volume, add pureed tomato.
I boiled tomato in hot water for a minute, peeled the skin, and ground it to make puree.
Cook until oil separates. May take 3 mins in medium flame.
Add cooked red kidney beans and mix well for 2 minutes.
After that, add required salt, water ½ cup and simmer for 5 minutes or until it turns semi dry.
Add black pepper and mix well.
