My district in Oregon does the same thing. Free lunch is offered to everyone with no means testing. The more well off kids still choose to bring their own lunches most days. Other days lunchroom trades are carried out between the school offerings and food from home but no child goes hungry and the program costs the same as when they had to pay people to deal with paperwork and bookkeeping.
