You could start by giving some away. You’ll get people’s attention, get them used to cooking more. Then you could also put out a request for donations or volunteer farmers who’d maybe get first pick of the crop. Good way to make friends and build community. Sooner or later maybe you can start a produce stand and turn a profit, and maybe before long you’ve got enough people involved to start a regular farmer’s market. That kind of local resilience would do a lot of good.
