something simple in the oven

A pupil was very late for his lesson so ended up finishing at some point after 10:00. At that point decided to make dinner. So, what to do.... ok, put some chorizo sausage from the local butcher, garlic, potatoes and olive oil, salt and pepper and quite a bit of rosemary (and a little bit of oregano) in an oven dish, stick it in the oven for the duration of three rounds of Bach Chaconne's arpeggios plus a few chromatic scales. It works!
