Because otherwise it is dull dull dull.
So when faced with a cup-a-soup, some rice cakes and a tomato, visual pleasure and flavour becomes very important. Hence the thick slice of rich ripe organic tomato, liberally sprinkled with sea salt, ground black pepper corns, decorated with a couple of tiny pickled onions, then a final flourish, a pinch of dried basil.
Low fat, but still yummy - and each rice cake with garnish only equals 30 cals, so you can indulge in several!
