Sardines have been a staple in Mediterranean coastal communities for centuries, prized for their abundance, affordability, and high omega‑3 content. They are traditionally grilled, marinated, or served whole, reflecting a diet rich in seafood and simple preparations.

Sardines are popular during summer festivals, beach picnics, and religious feasts such as the Feast of Saint Peter, where whole grilled sardines are served alongside rustic breads and wine.
