Does the taxpayer recognize gross income in the following situations?

a. Ava is a filing clerk at a large insurance company. She is permitted to leave the premises for lunch, but she usually eats in the company's cafeteria because it is quick and she is on a tight schedule. On average, she pays $2 for a lunch that would cost $12 at a restaurant. However, if the prices in the cafeteria were not so low and the food was not so delicious, she would probably bring her lunch at a cost of $3 per day.

Ava would include $___per meal in her gross income?
