Ashlawn Elementary sponsors a Lawns to Lettuce for Lunch campaign twice a year that I think is just awesome. Kids and neighbors are encouraged to grow lettuce in the Spring and Fall. The school supplies the seeds, instructions, and any other gardening support needed. After the harvest, volunteers wash the lettuce, add it to loads of other interesting vegetables that neighbors grow, and serve a salad lunch to nearly 700 kids, teachers, and volunteers at school. In addition, they make a native Costa Rican dish to serve with the salad. The Costa Rican dish is included because the school does a student exchange program every year, and the Costa Rican exchange students are typically at our school during the week of the lettuce lunch.
In the days leading up to the lunch, a chef goes around to different classrooms and makes different salad dressings for the kids to try. The kids vote on their favorite and that is what is served with the salad.
I like so many elements of this activity - the community aspect, the grow your own food piece, the education in the classroom, the inclusion of culture, and the introduction to whacky vegetables I'd never heard of like grape cucumbers. We are often very successful growers in the Spring. Not so much in the Fall.
