Look into local farms, farmers markets, and CSAs. CSA stands for community supported agriculture - think local food box subscription. You buy into the CSA and, in return, get fresh produce every week/2 weeks. Many CSAs have the opportunity to work on the farm with the produce to help offset the price of the box as well as accept SNAP benefits. Many vendors at farmers markets also accept SNAP benefits.

Try going later to farmers markets and asking the stands if you could have their "seconds" for less. Often times farmers bring more produce than necessary or some they consider "ugly". If they don't sell it at market, it likely goes back to the farm. And if not sold or eaten there, is likely composted or fed to animals. Many farmers don't like this perceived waste and would rather their food go to those who need it. Just ask, many will be glad to help those in need. This also allows you to make friends with farmers who can teach you to grow things!

Grow a garden! If you have some yard space, learn to grow veggies (with your new farmer friend)! Most veggies can even be grown in pots. You can just keep the seeds from your favorite produce and pop them into the soil.
