In aus a packed lunch is the norm for every kid. If they want a hot lunch its the canteen via a lunch order
Most parents pack what gets eaten and isnt overly messy or time consuming to eat.
Its all well and good to put together some planned out bento box thing, but if your kid wont eat it, its a waste of time, money and effort.
Sandwiches, fruit, veg sticks, salami, cheese, cookies, chips/crisps, baked snack bars, pouch yogurt, fruit boxes are the norm for our area
Most schools nut free entirely, some also say no to certain fruits.
On keeping it cool, insulated lunchbox and freezer bricks. Can also freeze the fruit boxes and yogurt
Canteen at school has pies, nuggets, wedges and gravy, 2 minute noodles, hot dogs, baked potatoes, soups, sausage rolls, flavored milk, juice, milkshakes, cookies, lollies, choc mousse
There healthy options but in dd class at least they not often chosen. If sports day is an indicator, its the salads and stuff left over after all the pies, hot dogs, hot chips are gone
