This Pumpkin, Ham, and Leek Quiche is a delicious and savory dish that combines the flavors of pumpkin, ham, leek, and cheese. The creamy pumpkin filling is complemented by the smoky ham and the mild onion flavor of the leeks. The quiche is baked in a flaky pastry crust, resulting in a golden and crispy exterior. It is perfect for brunch, lunch, or a light dinner, and can be served hot or cold.
