In Spain and Portugal, sardines, mackerel, cod, tuna, mussels and other seafood packed in cans aren’t emergency pantry items. They are highly valued for dining, and restaurants serve them.

The seafood is described as being sustainably harvested by small, long-established and often family-run companies.
