Final answer:
Most savory pies include meats, vegetables, and gravy or savory custard encased in a crust, with a notable exception being vegetarian pies that omit meat in favor of vegetables, beans, or other protein alternatives.
Step-by-step explanation:
Most savory pies are known for including meats, vegetables, and gravy or a savory custard filling. They often have a crust made either of a traditional pie dough or sometimes puff pastry. Typical fillings include beef, chicken, or lamb mixed with vegetables such as carrots, peas, and potatoes. The gravy or sauce is used to add moisture and flavor, tying all the ingredients together in a savory filling.
However, there's an exception to the typical savory pie makeup; not all savory pies come with a meat-based filling. The one notable exception is the vegetarian savory pie, which substitutes meat with alternatives such as lentils, beans, or a variety of vegetables, sometimes also including cheese or tofu to provide protein and additional flavor.
