DS (5) eats really well at home but will only have cheese in his sandwiches. To be fair, there are variations on this (cheese & pesto, cheese and chutney or just cheese in a roll, on bread) but I'd really like him to try other things too.
He won't eat hommous any more but will sometimes have cold pizza or fake meat chicken nuggets.
What can I put in to make his lunch more interesting? Or shall I just let him eat cheese sarnies every day?
