Only an observation but unless you are stopped at customs and they specifically look for tea, meat, fruit etc I reckon you will be fine.
When we were boarded last year looking for clandestines they only looked under one bench seat, the wardrobe and the shower room. Did not bother with the other bench seat, under the bed or the overhead locker.
I for one will be taking, bacon, cheese, tea etc You would need to fill in a customs card on the Chunnel or ferry before you landed where it would ask you to declare any of the items, and I doubt they will be bothered.
What will you say if they specifically ask you "do you have any foodstuffs? And what are they sir?
