Tomato paste or tomato masala is prepared and kept in the fridge by me for making any tomato based gravy subzi. It saves a lot of time if this is ready with you in the fridge like your ginger garlic paste, chilli paste etc. though freshly prepared ones are always preferred, working women can opt for this method as it remains in the fridge for about a month, if handled properly.
This paste can be used for making tomato rice too. Since the rice is favourite dish of my children, I always keep the paste in fridge. refer the link for tomato rice
I make most of the subzis with this paste, tomato rice etc. video :
