That's such a good idea! I don't eat a lot of sweets, but something like that would probably help with my savoury cravings too! Last night I ended up eating a huge chunk of cucumber to stop me eating biscuits
Just be careful of sugar levels though, the natural sugars are really concentrated in dried fruit and I learned te other day that they add a lot of sugar to dried cranberries so they're not so bitter! Still a better choice than sweets though!
