I would support gnu's post about the beans - I gave myself lathyrism from a veggie slowcooked casserole - no red kidney beans but a variety of other pulses. I now use tinned pulses of various varieties for safety's sake - except lentils, which seem to be OK. The alternative is to bring the casserole to a good simmer for the last 10 minutes of cooking - that way the flavour works better.
