In a wide pan, heat oil. Add finely sliced onions and fry till golden colour on a low to medium heat.
Add tomato puree / sliced tomato and stir well till well blended.
Add diluted spice mix. Stir well continuously for 2 - 3 minutes until the water dries up.
Add curry leaves. Mix well.
Add boiled chawli (along with stock - may be 1/2 cup) and add extra 50 ml (1/4 cup) water if required. Adjust salt to taste. Cover with a lid and cook on a low to medium heat for 10 - 12 minutes or until the gravy thickens and creamy. Serve hot.
