Method:
Put all the kofta ingredients in a food processor and make a paste.
Form the fish mixture into 1 inch diameter balls.
While you are doing this, heat enough cooking oil in a shallow frying pan, to shallow fry a few koftas at a time. 
Watch carefully and turn as each side gets golden.
The koftas are done when they are crispy and golden on both sides. Keep aside.
In a large saucepan, fry the onion in the oil till golden brown.
Add the tomatoes, salt, pepper, and all the other ingredients. 
Simmer for 15 minutes.
