Peel and cut potatoes and boil
Heat the oil in a frying pan and add few curry leaves, onions and mustard seeds until the seeds start popping.
Add the green chillies and fry until the onions brown a little.
Add the chilli powder, chilli pieces, turmeric and salt and fry for a few seconds before added the potato cubes.
Fry the mixture for 5 to 10 minutes until the flavours have merged together and the potatoes have a reddish hue.
Finally add the lime juice and serve.
