The Sunbites range of preservative, colour and artificial flavour free chips and crackers are fantastic and available at your local supermarket.
I shared a range of Sunbites goodies with my team at work and not only did the guys love the range, but they actually grabbed handfuls out of opened packets, began to eat them then returned to pick up the packet to see the flavour and turned them around to read the ingredients. They were a hit!
