Mine only get water one water bottle and sometimes a frozen small bottle in their lunch box to help keep whatever is in the lunch box cold.
Sandwich or tin of tuna, or a roll depending on what we have.
Wraps cut up with Hommus.
Carrot sticks (occasionally, if I send them all the time my oldest stops eating them).
Fruit sometimes the only fruit they will eat in their lunch box is grapes. They have fruit when they come home instead otherwise it goes to waste.
Home baking eg small scones, slice, biscuits, mini muffins
Cheese (the babel sp?)
Rice wheels or rice crackers.
Corn thins or Salada type crackers.
Bar eg fruit bar or whatever is on special
They do not have all above on one day. They usually have 2 things for lunch and 2 things for morning tea depending on what I have made. I feel bad when they come home saying they were still hungry at lunch
