I quite often make this nice looking salad to serve on the side of various dishes. Sorrel tastes lovely and its green leaves with contrasting purple stripes add some eye-catching color to the salads. The grapes bring sweetness to it, while Parmesan chips add their own characteristic and somewhat salty flavor.
As I have mentioned before it is sort of pointless to say too much about quantity here since this very much boils down to the size of the salad bowl – or how many diners. Occasionally your estimates might be a bit off, but it really doesn’t matter too much.
