The term "school lunch" refers to a meal that is provided by a school or educational institution for its students during their lunch period. This typically includes a main dish, such as a sandwich or entree, along with side items like fruit, vegetables, and a drink. The purpose of providing school lunches is to ensure that children receive proper nutrition while they are at school, and in some cases, it may also be used as a means of teaching healthy eating habits. School lunch programs can vary widely depending on the resources available to the institution, but generally aim to provide balanced meals that meet dietary guidelines for students.
