Halve the steaks and arrange a piece of steak on each plate, along with some of the juices that have accumulated on the plate. If the tomato sauce has separated, whiz it in the blender to remix, then spoon some of it over each piece of steak. For the best-tasting steaks, be sure not to overcook them. Balsamic vinegar is ideal for a salad with radicchio because the vinegar's sweetness offsets the bitter edge of the red lettuce. If you don't like radicchio, substitute Lola Rosa or red oak leaf lettuce.
Some balsamic vinegar can be as well aged and as refined as good wine, with accordingly high prices.
If you don't have that kind of balsamic vinegar, and don't feel alone if you don't, add a touch of brown sugar to supermarket balsamic vinegar to approximate the richer flavor of a fine-aged Italian balsamic vinegar.
