This obviously refers to the sliced bread that you left lying around the table at the end of the meal. It would be difficult to slice a loaf into a ball. You can heat them up in the toaster or oven and top them with cheese, pâté, pickles, hummus, guacamole, or even break them into salads like croutons.
Like the Italians, you can rub toast with garlic and spread it with tapenade, crushed tomatoes, olive oil, aubergine caviar, cheese, etc.
You can store your toast in an airtight jar or container until you need it.
Here is a delicious toast recipe available in the app:
