I've also read an article or two about how canned tomatoes are among the worst things you can eat, due to their acidity, and the fact that there is no such thing as BPA-free canned tomatoes.
There are a few alternatives-
-glass jars, with glass lids- if the lids are aluminum, they're most likely lined with BPA plastic
-POMI tomatoes, from Italy, readily available here. They come in square containers, similar to the ones that soy milk and soup come in. They aren't organic, but I have this belief that they do fewer horrible things to food in Europe...
