Cut tomato, potato and onion into really small and fine pieces.
Cut the stems off the brinjals.
Cut the brinjals into four segments 3/4 th through it so that it's open at one end but intact at the other.
To the cut fine pieces add red chilli powder, salt, dhaniya powder, finely cut dhaniya leaves(can put 1 spoon of dhaniya chutney if leaves are not there for flavor), sugar, and oil and mix well.
Use this as stuffing and add to the cut portions of brinjal.
Now place all the stuffed brinjals into a kadai.
If excess of the stuffing remains just add it at the top.
Add half glass of water.
Close kadai with a lid and keep in high flame for 3-4 mins till gravy starts boiling.
