Sainsbury’s (who seem to have re-acquired the apostrophe) were making much show of their new leaflet on Friday: Love Your Leftovers
The recipes seem a little exotic to one brought up on rissoles, & bubble & squeak
I am surprised that soup is not mentioned at all. They suggest making the most of a chicken or turkey by using the last scraps of meat for a risotto, but not using the carcass for the wonders of home made chicken & vegetable soup
