Rollmops

I like the idea of food presented in inappropriate packaging, like rollmops in a crisp bag (see-through, of course) or in a workman's tool box or wrapped in polystyrene.

Or presented in a standard jar which has the wrong colour or design (e.g. red and orange swirly stripes instaed of variations of blue and fishy logos).

Rollmops are tasty and I believe they are a good hangover cure.
