From ages 11-13 I was a boarder at a local all girls intermediate. The matron used to get us to make our own lunches every night before bed. There was great sport in smuggling nutella out of the lunch room in plastic seal-able bags or bundles of clingfilm. We'd then bite the corner off of the bags or poke a hole in the cling film and eat it plain. Nutella and Raro packets (think cool aid or cordial mix) were the currency of the Hostel - I managed to get a sweet deck of Pokemon cards out of three packs of raro and four bundles of nutella.
Now days I still eat it plain, but it's normally from the jar since I don't have to be ninja about getting it out of the pantry. Lol. Sometimes though, I relapse and stick it in a bundle and yeah. It's also brilliant on toast with melted butter.
