Vegetable pies are savory baked dishes filled primarily with a variety of vegetables. Common ingredients include potatoes, carrots, spinach, and onions, often combined with herbs and spices for added flavor. The filling is typically encased in a pastry crust, which can be made from flour, butter, and water, creating a flaky texture. These pies can be served hot or cold and are popular in many cuisines around the world. They can be enjoyed as a main dish or a side, making them a versatile option for meals. Vegetable pies are also a great way to incorporate more plant-based foods into one's diet.
