Make only what's needed
I note one school has already opted out of free meals in schools as the cost of revamping the school kitchen would be far too great.
Why do all the children in the school need to be fed when there are only a certain number of children in schools or kindergartens that require lunch?
I help make sandwiches with other volunteers four days a week which St Vincent de Paul delivers to some schools and kindergartens. But we only make the numbers required for children who bring nothing. This does not take too much time.
