OK so I'm not sure if that's the right spelling, but Rispinos were lovely! They were like rice cakes, fairly big and round but you could also get smaller ones. They say snack-a-jacks are low in fat, well me and my mum found out that Rispinos were even lower!
You could get Rispinos in all sorts of flavours - pizza, cheese and onion, chocolate, and caramel plus a few more besides! You could get small or large bags of them but I haven't seen any since I used to buy them in College back in 2003. If they still exist, I want to know where so I can go and buy a bulk order!
