What type of item is a "Slice Amer Cheese" classified as on the menu?

A "Slice Amer Cheese" is classified as a condiment or extra on the menu. This classification is appropriate because condiments and extras are typically items that enhance the flavor or texture of a main dish, rather than being standalone menu items. In many restaurants, including Jack in the Box, cheese slices are often added to burgers or sandwiches to complement the meal, rather than being served as a primary offering. This distinguishes it from side items, which are meant to accompany a main dish, or main dishes themselves, which are complete meals. Additionally, it doesn't classify as a beverage, as it does not fit the category of drinks.
