means A small round case of light puff pastry with a hollow center, filled with a savory (or sometimes sweet) mixture in sauce.

from Straight from French, literally 'flight in the wind' (vol = flight, au vent = on the wind). The name is credited by tradition to the famous early-19th-century chef Antonin Carême, who supposedly exclaimed that the pastry was so light it could fly off in a gust. Built from puff pastry — pâte feuilletée — whose many butter-laden layers puff into airy crispness, the dish earns its breezy name honestly, though whether Carême himself coined the phrase is more kitchen legend than documented fact.
