There is little as comforting – or as delicious – as a well-seasoned meatball cooked in a rich tomato sauce. I find myself making double or triple batches to stash in the freezer, ready to iron out dark moods or family flare-ups. Should you wish, you can get away with only a couple of meatballs a head when they’re served with plenty of buttery polenta and that silky tomato sauce – an easy way to enjoy meat without going crazy. Happy purse, happy planet.
