which of the following is least likely to be saved as a main course during la cena

It is difficult to determine the context of "la cena" without further information. However, assuming "la cena" refers to a typical dinner, the following options are least likely to be saved as a main course:

1. Ice cream - Ice cream is commonly served as a dessert rather than a main course.
2. Salad - While salad can be served as a main course, it is more commonly served as a side dish or appetizer.
3. Bread - Bread is often served as a side dish or accompaniment, but it is not typically the main course.
4. Soup - Soup can be a main course, but it is more commonly served as an appetizer or starter before the main course.

Ultimately, the actual answer will depend on cultural preferences and personal choices.
