Ciabatta

Ciabatta is an Italian white bread made from wheat flour, water, salt, yeast and olive oil, created in 1982 by a baker in Adria, province of Rovigo, Veneto, Italy, in response to the popularity of French baguettes. Ciabatta is somewhat elongated, broad, and flat, and is baked in many variations, although unique for its alveolar holes. Ciabatta is made with a strong flour and uses a much wetter dough than traditional French bread.

While panino indicates any kind of sandwich regardless of the bread used (whether slices or a bun), a toasted sandwich made from small loaves of ciabatta are known as panini (plural of panino) outside Italy.
