The gravy should not be runny. If it is, then mix a tbsp or so of gram flour in 3 tbsp water, add it to the gravy and simmer for 3-4 minutes, till thick.
You can increase or decrease the spice level by adding more or less green chillies, as per your tolerance. The kizhangu will taste as good even without the sambar powder- it just adds some depth to the flavour.
This can be served with plain rotis too, but is a perfect accompaniment with pooris. Serve with your favourite pickle.
