Back in August on PBP, I only once stopped at a regular small shop (i.e. not a bakery) for grub. They didn't stock ANYTHING close to our typical flapjack/energy bars type things: the only thing they had that I could carry with me (and had any appeal) was a packet of fig rolls.
Went down a treat, and FAIRLY easy to retrieve from packet in back pocket on the move.
(Mind you, shortly afterwards I got passed by a group of welsh persons wearing matching pink berets, so who knows what is in a French Fig.)
