Cookbook? Forget it - you're aiming too low!
In the UK, we have a bit of a backlash against fast food and the obesity epidemic, and there are lots of cookery programmes about healthy home-cooked food, some of which (Jamie's school dinners
) have a distinctly political agenda. They are getting good ratings.
I say we go for a combination food / lifestyle / politics / religious programme and do 13 weeks of something like 'Pirate Pasta Cuisine'. What do you think?
