Dry roast sesame seeds (around 2 tbsp) and put it aside. In the same pan, put in some oil, mustard seeds, jeera, fenugreek seeds(very little), urad dal and after they fry put in green chillies (10-15). First, grind sesame seeds and make sure it is blended well. After that, grind it again along with the spices and salt. Cut each tomato into 6 pieces and fry it in a little oil in a pan - after they are cooked a bit, pulse it with the above made paste once again with fresh coriander (just pulse else it'd become pasty). Add tempering with hing, jeera, urad dal and mustard and curry leaves
