1. If you like adding more onions you can add. 2. Also instead of tomato sauce, you can add tomato chilli sauce. But it will be more spicy n sweeter version. 3. You can reduce the garam masala when preparing for children. 4. You can also sprinkle chat masala just before serving. 5. My small one strictly said not to add the green chilli, so I did not add. Chilli powder and garam masala itself gives enough spiciness for our dish. If you want more spicy, you can add green chilli.
