I was struggling to find a dried tomato that was sulfite free. Here it is! Mezzetta brand contains:
no sulfites - According to befoodsmart.com, sulfites are used to preserve food and retain the food's colour. Dried Fruits naturally contain sulfites so they don't have to state that sulfites are added in the preserving process. So it is important to look for 'Sulfite Free' when shopping for dried fruits. Sulfites rate a 'D' on the befoodsmart scale because they are dangerous for people sensitive to them. Sulfites may cause serious reactions for those who suffer from asthma. They may also cause: migraine headaches, hives, anaphylactic shock and nausea.
I bought this brand at Country Grocer in the canned vegetable aisle for $5.79.
