hi Janaki,
I completely sympathise with this problem. I solved it (or partially solved it) by using timers, electric rice cooker, 9 ply waterless cookware. I prepare everything before going to work, set everyting on timers & when i come home for lunch everything is ready! Will be happy to eleborate on the menu if interested, it is a good vata meal with vegges, grains, ghee, red lentils etc
Put extra pressure in the morning tho.
Best Wishes,
