Nice one Jon - similar situation here with tomato glut.
About 1kg of Madhur Jaffrey recipe chutney (home grown chillies from last year, this years tomatoes):

Highly recommended - looking forward to Boxing Day with cold cuts already :)
I intend to follow your lead on the roasted tomatoes - what temperature and how long in oven? (couple of hours at 120?)
