Chop the onions and green chillies and set them aside.
Into the frying pan add the mustard seeds, asafoetida and cumin seeds ( jeera).
Let them roast on medium heat till the mustard crackles.
Add the chopped onions, curry leaves, green chillies and peanuts and saute well.
Add the salt, turmeric powder and red chilli powder.
Add the shredded rotis and the sugar.
Saute well till the spices are well mixed and it is all warmed through.

Notes
Instead of adding the tomato at the end, you can add it with the onions and let it soften. We prefer the fresh flavour of the tomatoes and hence keep it to the end.
