Whatever

Not entirely Jane since "whatever is delicious to the office." implies you should bring only items delicious to the office but perhaps not its inhabitants

…..falling pretty much in the same category as my "Not entirely Jane", which implies not that your sentence is unacceptable but instead that its's not entirely Jane

We're having an office party next week so please bring anything delicious

Or "please bring something delicious".

Right in there, Con. Like me you must be amused by the occasional slip

I think anything or something work equally well. You might say that the word 'delicious' is a bit excessive - or maybe us Brits are too given to understatement.

It's not that, Con. Brits are literate where we're mostly a bunch of clowns unable to comprehend even the simplest sentences nor express our ideas coherently; in part accounting for all the hostility on a typical Internet site such as this one
