Rustico (plural rustici) is a snack from Salento, in Apulia, Italy, made with puff pastry and stuffings that vary by style. A common preparation uses puff pastry, tomato, and mozzarella. It is part of the Salentine street food tradition and can be found in every Apulian bar, bakery, and rotisserie.
It is produced with two discs of puff pastry, the lower disk is of about 10 cm (approximately 4 inch) in diameter and the upper one of 12 cm (about 5 inch), to which adds cheese and tomato.
In Salento it is usually eaten as a mid-morning or evening snack, both in summer and winter. The würstel variant of the pastry, made with small frankfurter sausauges, is the best known in Salento and throughout northern Italy (perhaps due to the Austrian culinary influence).
