A turnover is a type of pastry made by placing a filling on a piece of dough, folding the dough over, sealing, and baking it. Turnovers can be sweet or savoury and are often made as a sort of portable meal or dessert. They are often eaten for breakfast. Savoury turnovers are often sold as convenience foods in supermarkets. Savoury turnovers with meat or poultry and identified as a turnover in the United States (for example, "Beef Turnover" or "Cheesy Chicken Turnover") have to meet a standard of identity or composition and should contain a certain amount of meat or poultry.
