Which of the following herbs is often used to flavor Mediterranean cuisine?

Oregano is a cornerstone herb in traditional Mediterranean cuisine, cherished for its robust flavor and aromatic qualities. This herb is frequently used in various dishes, including pasta sauces, salads, grilled meats, and vegetable preparations, closely associated with the flavors typical of Mediterranean cooking. Its earthy and slightly bitter taste complements the rich ingredients often found in Mediterranean dishes, such as tomatoes and olive oil.

Basil is indeed a popular herb in Mediterranean cooking, particularly in Italian cuisine, but oregano is arguably more universally recognized for its prominent role across a wider range of Mediterranean dishes. Cilantro, while a flavorful herb in many cuisines like Mexican and Indian, does not hold the same significance in the Mediterranean context. Pickles, although tangy and flavorful, are not classified as an herb and therefore do not fit within the category of herbs used to flavor dishes.
