Just that really. My oven appears to be on its last legs. The fan on it gave up the ghost a few weeks ago and now it is being very tempermental. Some days it works fine, others it displays an error code and refuses to heat up. And due to a complete lack of any spare cash there is no chance of us purchasing a new one before the big day and I am convinced it is going to breakdown completely on either Christmas Eve or Christmas Day 
So while it is mostly still working I want to get ahead and prepare as much as possible. If the worst comes to the worst I have a neighbour on standby who will let us use their oven for the turkey but I obviously can't take over their kitchen on Christmas day and be popping in every five minutes.
So is there anything I can do? Any recipes I can use? Or am I completely doomed.
