This central part of the meal sets the tone for the overall dining experience and influences the choice of side dishes, desserts, and other menu items. Just as the authors in the provided context made a breakfast choice based on various factors such as time, cost, and health, menu planners also weigh different considerations when deciding on entrees. These could include the availability of ingredients, the target audience's preferences, the type of cuisine, seasonal considerations, and overall budget constraints.
