how do french people eat
During the week, many people will eat a three-course meal at home every evening; though if all concerned - or most of them - get a full three-course meal at lunch time in the works canteen, in a restaurant, or at the school cantine (and, yes, a proper balanced-diet 3-course meal is standard fare in French school canteens), then the evening meal may often be lighter, a hot snack or pasta or something similar, followed by yoghurt or a dairy desert and fruit.
