This Italian flat-leafed parsley has, of course, flat leaves, which distinguish it from the better-known curly-leafed parsley. At first, the foliage might be easily confused with cilantro. However, its flavor is distinctly parsley, and it is favored for its deep flavor, which some say holds up better in cooking than curly parsley. It is popular in Mediterranean and Middle Eastern cuisine. Easy to chop, the nutritious flat leaves are high in iron and in vitamins A, C, and E. A high chlorophyll content makes it a natural breath sweetener, too.
