What is packed lunch in American English?

In American English, a "packed lunch" is a lunch that is prepared and brought from home, rather than being purchased at a restaurant or cafeteria. It's often referred to as a lunchbox, especially when talking about children's lunches.

Here are some examples of how it's used:

* "I made a packed lunch for my daughter, with a sandwich, fruit, and chips."

* "He brought a packed lunch to work today because the cafeteria was closed."

* "My packed lunch was a bit boring, but it saved me money."

It's important to note that the term "packed lunch" is more common in British English. In American English, it is used, but it's less frequent.
