Arugula, also known as rocket, garden rocket, rocket salad, rugola, and rucola, is a type of leaf vegetable, and although often mistaken for a sort of lettuce, is in fact an herb, being a member of the mustard family. It is rich in vitamin C, iron and potassium.
Arugula has been grown as a vegetable in the Mediterranean area since Roman times, and is still very popular in Italy and the Mediterranean. Arugula has a rich, peppery taste, and has an exceptionally strong flavor for a leafy green. It is one of the only herbs that we munch on when walking through the greenhouses. It is generally used in salads but also cooked as a vegetable with pastas or meats and in coastal Slovenia, it is added to the cheese burek. In Italy, it is often used in pizzas, added just before the baking period ends or immediately afterwards, so that it won't wilt in the heat. It is sometimes used as an ingredient in pesto, either in addition to basil or as a (non-traditional) substitute.
