The proving ground for a lunch-centered curriculum is another Chez Panisse Foundation project, a one-acre garden next to Martin Luther King Middle School in Berkeley called the Edible Schoolyard. For the past nine years the students have planted, tended, and harvested the produce, then cooked up meals (most of which tie into academic lessons) in the kitchen classroom that’s equipped with restaurant-style tools. The students voted the Edible Schoolyard their second-favorite class, after physical education.
