For an interesting comparison, I used to babysit a 3 year old who had these sorts of lunches at a bog standard state nursery (catered by the kind of association that also serves hospitals, care homes). This menu is offered in some pretty deprived pockets of the area surrounding Paris, but local authorities are still presumably managing to make provision of balanced, nutritious 4-course meals (+ goûter/snack) work within a budget, with vegetarian, organic, seasonal and local produce all making regular appearances.
When I'd go to pick her up at lunchtime the room would be full of toddlers eating everything on their plates with no fuss inc. daily varied cheeses (though admittedly most varieties there are quite mild), vinegar-based dressing, raw, strong-tasting and interestingly textured veg and carbs (endives, red cabbage, chickpeas, quinoa, mushrooms, bulgur) etc. Still quite a bit of cake though.
To be fair, mushy's menu looks good on whole too, so maybe it's silly my posting the above, as these variations are possibly not budget-related in the UK at all? No idea how it works. I was just so impressed by the French system as couldn't help comparing everything favourably to my cheaptastic lunches at an English state primary in the 2000s...turkey twizzler/chips/arctic roll extravaganzas
so good
