Alice Waters: I want all students in the state of California to have a free sustainable school lunch. I want them to sit down together and have time to eat and talk. And I imagine that school lunch could actually be part of an academic subject. So when you’re studying, for instance, the geography of the Arabian Peninsula, maybe what you’re having for lunch is some hummus.  Maybe you’re having pita bread. Maybe you’re having a little spicy carrot soup or a tabbouleh salad, but you’re buying those ingredients. The cafeteria workers — the cooks in the cafeteria — will buy directly, like we have been doing for 47 years at Chez Panisse, directly from the producers who are local and sustainable.
