Their website doesn't include PN-free labeling - just TN-free.  I assumed that was because they don't have any products with PN?

Well, looks like they label things as being free-from, but if you read the fine print, they're still produced in a facility with allergens...  I guess it depends on your comfort zone with this statement from their website:

I have several food allergies. Is there a possibility of cross-contact in your facility?

The safety of our customers is our top priority, and we recognize the needs of our customers, who have allergies or sensitivities to nuts, gluten, certain spices, etc. Amy's always discloses all ingredients (except for specific spices used in the product) on the ingredient statement as required by the FDA and will answer any questions that will help consumers decide what products they can safely consume.

A wide range of activities and cross-checks are completed to ensure that cross-contamination and/or inadvertent use of the wrong ingredient does not occur in our facilities.

At Amy's we take every precaution to ensure that cross-contamination of ingredients does not occur in our production facility, but we want you to know that this product was produced in a plant that processes foods containing wheat, milk, soy, tree nuts and seeds. Amy's Kitchen does not use any peanuts, fish, shellfish or eggs.

Tried their organic PN/TN/Dairy-free burritos - better than a restaurant. Their website is well done for answering FA questions.
