I use to fill each morning for school a small plastic box with cherry tomato,or sticks of carrot or sticks of celeri + another box with 2 slices of banana bread one week, I change the second week with slices of white bread with peanut butter or nutella, few grappes, few walnuts, they get bored with the same food all the time, if they dont eat that as a snack at school than display them on the kitchen table and hide all the sweets and jonk food, when they play they always come to the kitchen and pick up. You will be happy to know that she will have few peaces of each veg. good luck.
