A single-dish meal is a type of meal that consists of one dish, usually containing multiple ingredients. The two most common examples of single-dish meals are potpie and STEW. Potpie is a savory pie with a crust on the top and bottom, filled with a mixture of vegetables, meat, and gravy. STEW is a type of soup made by simmering vegetables, meat, and other ingredients in a liquid. Both potpie and STEW are popular single-dish meals that can be served as a main course.
