Rustico

Rustico is a Salento snack 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. Then it is brushed with egg and baked in the oven. It should be eaten warm to best appreciate the taste and the melted mozzarella.
