Lidl's Low Gi rolls.

[Boo1979]

Where do you buy your Joseph’s pittas from?

Amazon. Beware tho - if you go for the seller offering ‘prime’ the price triples compared to other sellers ( or maybe its the same seller using different pricing - mad either way)
Ive recently found out you can also get them here but I havnt used them as yet

You can also buy them here, along with fresh baked bread and rolls that are supposed to be low carb. They also sell "diabetic" sweeties, but beware the gummi bears unless you are actively in pursuit of Intestinal Armageddon. http://www.avidlite.co.uk/acatalog/BREAD.html
