Dinner that keeps till 7 for the kids on my long theatre days?

On list days I'm out before the kids wake up and back after they've eaten. Our caregiver is wonderful with them but doesn't cook, so their dinner is whatever I make the night before. Right now it's a rotation of pulao, upma and dal rice, and my son has started asking 'again pulao aa?' What do you make ahead that still tastes alright at 7 the next evening for two little ones? Nothing that needs more than a quick reheat.
