Not direct advice for your problem, but whenever we had veg with our own dinner we would cook a whole load of it (without salt etc), mash it up, put it into ice cube trays and freeze it.
Then whenever we needed a meal for our 1 year old we could get a variety of food cubes out from the freezer and defrost them for lunch. From what I remember it worked really well.
Yup that's what we used to do when we first started weaning him at 6 months, always used to work well, but from what we've been told they're supposed to be having proper meals now. Obviously we can't give anything too chewy as he hasn't got his molars.
