Italian parsley (sometimes known as flat-leaf parsley) is a green herb with serrated leaves and a clean, slightly peppery taste. Its flavour is stronger than that of its ruffled cousin, curly-leaf parsley. ... Italian parsley has leaves that are larger and fresh, grassy.
The leaves are soft and pliable and useful whole or chopped. In fact, the entire stem is good cut up and used in chicken salad or other places where celery or some crunchy vegetable would be appropriate. You can even use Italian flat leaf parsley roots in salads or sautés.
