Warmer and Still not fancying chocolate

It seems that my chocolate cravings are completely based on my hormones as I haven't fancied it at all for the last week. I also ate better today and feel much warmer so my blood sugar is higher as a result. I bought a lot of soups and snack foods today so that when I'm snuggled up in bed in the evenings trying to stay warm I can munch on something to stop me getting too low. Any ideas of low fat filling snacks that don't need much preparation (if any!) would be appreciated.
