Lunch Box for School

I put some foods that I usually see in the students' lunch box and also the foods in their canteen. You can see here some milk and cookies, hotdogs, fish and salads for the vegetarian students. Nowadays, some of the students were just requesting or asking for money instead of a ready packed snacks. Most of their reason why they want that way is because they can buy or choose the food/snacks they want. It's a great situation for them, but the problem is are they choosing/buying the good and nutritious foods?
