We have similar restrictions at my children's preschool. Nothing containing, or even processed in the same facility, nuts, eggs, dairy or chick peas. Given that we are also on a grain free and vegetable oil free diet that leaves very little my children can eat at school. Most of the things everyone else brings along or wants to make at school cooking projects don't work for our children. Fortunately they are only there in the mornings. They have fresh fruit and some coconut & honey biscuits I make.
