Recently I bought a pack of these: Roasted peanuts with shells. I'm on a tight budget so whenever possible I do my best to not throw food away, and thus I eat the shells of peanuts (among other things such as lemons and sometimes bananas). The shell is quite good, not much flavour perhaps but easy to chew. I'm not sure about the nutritional value of the shells, but they're bound to provide some fiber at least. If you are presented peanuts with shells, do you eat the shell or peel the nut?
