A catering sandwich Box lunch typically includes a main sandwich, a side item like a salad, a fruit or vegetable, and a dessert or sweet treat, plus convenience items such as disposable cutlery.
Step-by-step explanation:
Typically, a catering sandwich Box lunch includes several components to make up a satisfying meal. The main component would be a sandwich which may consist of layers such as ham, cheese, tomato, pickles, and bread. Alongside the sandwich, the box lunch often includes a side item, which could range from a salad, a bag of chips, or a pasta salad.
An accompanying fruit or vegetable would balance out the meal, such as an apple, pear, or carrot sticks with dip. Lastly, a sweet treat like a cookie or brownie would complete the meal. Some packages may come with items for convenience, such as disposable cutlery, napkins, and condiments.
In a classroom experiment context, if the lunch is being analyzed, the contents might include products made with ingredients like flour and margarine, and the food could be intentionally “spiked" with bacteria for learning purposes.
