Renting the space out or landshare are very good suggestions indeed, although I don't think you'd want to come back to a veggie patch right in the middle of your lawn(although if it someone you trust things would be entirely different). Could you get a neighbour to pop round every fortnight and do a bit of weeding?
As for what to plant out, I agree, nothing. Your best bet is trying to suppress the weeds.
