Nowadays it is difficult to imagine a school without a canteen, especially in urban environments. The lunchtime is essential for families to be able to balance their work schedules with the students' school hours. For many families, it is almost a necessity. In addition, the canteen is a space that contributes to guaranteeing a healthy and balanced diet for schoolchildren. However, it is not part of the school schedule and no regulations require it to be part of the school's educational project.
