This is adapted from Ursula Ferrigno's Italy Sea to Sky. I've adapted it, as she specifies fresh beans, which you can't often get here. NB If you want to use the entire contents of the cans, if you've bought canned beans, I'd throw in a couple of cans of tinned chopped tomatoes, in addition to the one listed in the ingredients. Stick to the same amount of farro. I freeze it without the extra cans, so there's less to freeze, then throw in the extra tinned toms when it's thawed and I'm reheating it.
