My sun dried tomatoes are from Trader Joe's: sun dried Roma tomatoes, pure olive oil, herbs, spices, sulfur oxide (for color retention). Made in shared equipment used with tree nuts, milk, wheat and soy.
Yep, no ground nuts (no peanuts there) and no sulfites. (Is there a tongue in cheek emoticon?) Well it hasn't killed me yet. If I were to avoid all sulfites (and all fried foods) I would probably be eating a drastically different diet.
If you made a list of everything to avoid you would probably end up consuming only water.
p.s. I'd be happy enough if TJ's left out the sulfites "for color retention" and give me grey tomatoes.
