Mediterranean diet

My children's school provides lunch, and no other food is available, nor are they allowed to bring more than a midmorning snack from home. Lunch is planned by a dietologist and supervised by the teachers; the only drink served with lunch is tap water. This is not a fancy private school, but the state one - the one that everyone complains about.
At home we usually cook from scratch, with help from our freezer: some things are cooked in large amounts, portioned, frozen, and microwaved at need. We also eat plenty of less healthy stuff, but fresh fruit, some vegetables, and yogurt are general favorites.
None of this is special, and indeed most other families cook more: typically, a main meal should include two cooked courses and one cooked side dish. We tend to have one cooked dish and sides that need only short or no cooking: for instance raw tomatoes and bell peppers, briefly cooked carrots and peas. Drinking tap water or bottled nonsparkling water is also standard practice here.
Reading this article and especially the corresponding comment thread made me feel quite lucky. It even made me a bit less ashamed of my and WS's own poor cooking skills.
