Remove the roots from the lamb`s lettuce. Wash and spin dry. Wash the grapes, pat dry and cut in half. Crack the nuts and roughly chop them.
Mix the vinegar, apple juice, salt, pepper and sugar together until the sugar has dissolved. Then hide the oil. Just before serving, fold in the grapes and lamb`s lettuce.
Serve sprinkled with walnuts.
TIP:
With fresh baguette and a little butter, it becomes a small starter.
