Wheat Nuts are little fake shaped things that were kind of like nuts made by Pillsbury with a cracking and oily inside but has a surprisingly authentic nutty taste and crunch. And it's digestible. Even people who can't eat regular nuts say they are delighted to be able to snack on delicious WN without worry. They were on the retail market for more than 40 years until they were pulled from the shelves by Anacon Foods later on.
Debuted in 1970 and was discontinued in 2013.
