Is LAY'S� Barbecue Flavored Potato Chips (Not Baked) Vegetarian?

I don't know about the regular ones but the baked Lays barbecue is made with chicken fat so it is entirely possible that the regular ones are too. It is also common to use beef stock in barbecue flavoring which could be lumped under natural flavorings. The only way to know for sure is to contact the company.
