We've unexpectedly got friends coming round for dinner tonight and I've got a lot on and am pretty knackered. I know they'd be happy with a take away but they always make a big effort for us and I'd like to do something ... Any suggestions about what would be not-too-disappointing dinner but would be pretty easy to make. It can take time in the oven, etc., as I'll be at home, but not a huge amount of preparation time.
