There's a brill tomato sauce recipe in the MN cookbook with lots of veggies and beans that you blend. And very easy to batch cook. I just stir in mascapone cheese at the end, which diverts from the book but is yummy.
Oh help - AAAARRGGGHH, I hate shit things happening like that. I have no idea how to fix though.
If it's any help my two DC, now teens, were both at times fussy with food. They eat pretty much anything now, although DS prefers meat and two veg and pie type meals, DD pasta and that kind of thing. The hours I spent worrying, I wish I knew now they would eat curry and chilli and pulses and soup and salad ect.
Hope you feel better soon sporting
Em I rarely buy sandwiches too, and also get excited 
Spent £20 in Boots today, however £10 was a New Look voucher for a birthday present, then there's a 3 for 2 on Soap and Glory, so got a little set thing for the present and shampoo and conditioner for DD, both for a fiver, because of the offer.
£10 on conditioning cubes for the pony.
