Where can I find pepperoncini, ideally on the UWS (e.g., Fairway)? A tomato sauce I'm making calls for it. I can't tell from my online research whether I should look in a deli section or in the produce section. I guess my preference would be to find the deli version, if that means it will last longer. The recipe only calls for a little, so it would be nice if I could store it for later consumption.
