Is it safe to use frozen bread to make a sandwich that is then put into a lunch box to defrost?? This would be for my 5 year old to take to school?? I don’t think it is safe but my husband thinks it’s fine??

On this occasion, your husband is correct. In fact, this is a perfect way of keeping your child’s lunchbox nice and cool. The frozen bread will defrost by lunchtime, and will taste just as good as fresh bread. Another top tip to cool down a lunch box is to place a frozen drink inside the lunch box. Before you do this, make sure the drink is in a tightly sealed bottle!

Thanks for your frozen food question.
