food costs

[mushpea]

I used to provide home cooked meals for the children and would put so much a meal through my books to cover this,,I have now stopped doing cooked food and provide a snack after school and a cold lunch
snack--fruit, biscuit, cake,
lunch -- sandwich, fruit, yoghurtor cake and crisps

how much would you/should i put through my books for the above?

I work my food bill out per head and claim a percentage per person rather than a standard cost
