/**
 * Module for generating food-related data.
 *
 * ### Overview
 *
 * This module provides methods to generate various food-related information, such as items on a menu.
 * To generate the name of a dish, use [`dish()`](https://fakerjs.dev/api/food.html#dish) and to generate a long description for a dish use [`description()`](https://fakerjs.dev/api/food.html#description). Note that these will not correspond with each other.
 * You can also generate individual components of a dish such as [spices](https://fakerjs.dev/api/food.html#spice), [vegetables](https://fakerjs.dev/api/food.html#vegetable), [meats](https://fakerjs.dev/api/food.html#meat), [fruits](https://fakerjs.dev/api/food.html#fruit), or generic [ingredients](https://fakerjs.dev/api/food.html#ingredient).
