There are many lists online that show vegan snacks and chips, but Hungry Jack’s is not listed on some of those lists. It seems like these chips are not vegan. This means that they could be cooked or fried in an oil that may come from an animal product. Some vegan snacks are not fried in oil. Some vegan snacks are not even cooked in oil at all.
They may be baked. However, it seems that Hungry Jack’s chips would have made one of the lists online if they were vegan. Instead, the same products from other companies are pretty much listed on every list.
