Unfortunately some of my plastic use was due to hidden packaging. I bought a pie at the grocery store that appeared to be in a simple cardboard box (without a plastic window) but upon opening it I found that the pie tin was encased in shrink-wrap plastic too. Understandably, it's to keep the food fresher, but I would not have purchased it if I had known it was covered in plastic. Maybe a way to avoid that plastic waste is to buy directly from a bakery where I can use my own box to bring it home. Or I could make my own pie next time! Although that may not be the most realistic solution...
