Oregano is most associated, I think, with Greek cuisine, but it is also a staple of Italian and Mediterranean cuisine. Unlike other herbs, oregano is most flavorful when dried, and you will see it sold at specialty markets on the stems, which is the best way to buy it. So you want to use dried oregano in your dishes, and Italians always have it in the pantry.
What is it used for? Italians use oregano in salads and with fish or chicken. We make a tomato salad with oregano. We season fish and chicken with lemon, olive oil and oregano. Oregano is also a component of sauce for pizza.
