Food flasks. My DSs go back to school tomorrow, and the tyranny of making packed lunchs begins. I'm really lucky, cos they'll eat anything I give them, and they both like "leftovers" too, but rather than give them cold spag bol or cold curry and rice, I'd like to heat it up in the morning, or make soup, and let them have a hot lunch. I got cheap food flasks from tesco last year, but by lunchtime the food was lukewarm. I've looked on the Lakeland website, and can't see any. There were a couple on Amazon, but they've stopped selling them too. Can anyone recommend any that will keep things warm till lunchtime?
