To a deep bottomed pan add ghee and heat. Splutter mustard seeds. Add the onion pieces, split green chillies and fry till the onion pieces turn brown.
Add the tomato pieces and allow to simmer till the volume of tomato pieces reduce to about one fourth and total ingredients blend well into a homogeneous mass.
