Watercress is native to Asia Minor and the Mediterranean region. Watercress grows wild in Greece and has been popular since ancient times. It is said to have health-boosting properties and the Greek general Xenophon made his soldiers eat watercress as a tonic to keep healthy. When Hippocrates founded the first hospital on the island of Kos around 400 BC, he grew wild watercress in the natural springs. He used it to treat blood disorders as he believed in its healing power.
Watercress is also high in vitamin C and calcium.
I like having watercress in salads and this dish is one of my favourites.
