Description

The pastry is simple and quick to prepare. Be sure to add cheese to the onion filling, as it will make the flavor much milder and more interesting. You can use ready-made frozen dough or prepare it fresh right before cooking. Use red sweet onion and fresh or dried herbs. Serve the pie cooled or slightly warm, either warm or chilled. Perfect with tea.
