A warming and hearty soup that's full of flavour and really fills you up thanks to the farro, which is an ancient form of wheat. I took inspiration from an Italian recipe on this site, tweaking substantially to fit what I had to hand. The result was delicious!
If you can't find the quick-cooking variety, use regular farro and cook it separately according to packet instructions. Then add to the soup mixture and allow to simmer all together for 10 to 15 minutes to let the flavours combine.
