What do we call a prepared item of food that is served in a meal?

A prepared item of food that is served in a meal is referred to as a "dish." This term encompasses various kinds of food presented together, such as an entrée, side, or dessert, and signifies something that is ready to be consumed, often showcasing a particular cuisine or cooking method.

To better understand the context, an ingredient refers to the individual components that are used to make a dish, such as vegetables, meats, or spices; these are not standalone food items served in a meal. A recipe is a set of instructions detailing how to prepare a dish, outlining the ingredients and steps needed to create that specific item, rather than being the end product itself. A menu, on the other hand, is a list of various dishes available for selection in a meal or at a restaurant, making it distinct from the actual dish which is what is enjoyed by diners. Thus, "dish" is the term that correctly captures the essence of a prepared food item ready to be served.
