Is It Illegal For My Employer To Tell Me To Eat My Lunch Off The Premises?

In California, where I work, it is legal for an employer to tell an employee to stay on premise while eating lunch; however, the employer must compensate that with the employee’s regular hourly wage.

However, does anyone know if it is legal or not to tell an employee to leave the premise for their lunch break? Further, if it is legal, is there any sort of concession or compensation to the employee?

To provide some context, if it is important to answering my above mentioned question, my employer complained about the smell of my food (though all other employees eat in the office without having received complaint) and told me to eat outside. I bring food from home and often need to heat it up with a microwave, which is in the office. Furthermore, there is no reasonable place for me to eat my home-brought food comfortably unless eating in my car or just on the sidewalk is considered reasonable. I do not want to eat non-homemade food consistently as my colleagues do (while in the office) for financial and health reasons.

I do get a paid 1 hour lunch, I work “8 hours” (7 work + 1 hour lunch), full-time.
