They are readably available and filling. This doesn’t mean they are good for you, of course, but chances are, they are vegan. Most mass produced potato chips are fried in vegetable oil. Very few mass produced chips are fried in lard (Utz seems to have a kettle chip that is fried in lard. Barf) or anything isn’t vegan. Potato chips also come in a variety of mostly vegan flavors, but there are plenty of non-vegan ones too. Beware of the following. 1  anything cheesy or creamy. 2  salt and vinegar – look for whey powder! 3  bbq chips – some have beef fat or honey.
