Squid sandwich or bocadillo de calamares in Spanish, bocata calamares in Cheli, is a culinary specialty very common in Spain consisting of a bocadillo sandwich of squid battered in flour and fried in oil that is usually olive, or the more sophisticated version that is all of the above plus a spicy tomato sauce and mayonnaise with garlic similar to that of patatas bravas.

[2][3] In Zaragoza, the sophisticated version of the calamari sandwich is traditional, with the spicy sauce (tomato, mayonnaise and garlic), and it is called bocadillo de calamares bravos or spicy squid sandwich, which is served in the bars on Calle Cinco de Marzo.

[5] Recently, baguettes from the establishment are usually made from previously frozen dough, which is usually cut on one side, giving each place a characteristic touch.

Sometimes a bit of squeezed lemon is added to the fried squid dish for flavor, and mayonnaise is also common.

The method of preparation is similar to that of the Madrid version and it can be found in various bars and restaurants in Cantabria, as well as in the Basque Country.
