After pickling, freezing and canning, baking tons of zucchini bread, making lots of salads, cooking and giving every person that you come into contact the bounties of your garden and you still have more to give away, consider donating your extras to a local food bank.
There is a great demand for food in our communities which led to the creation of Sharing the Harvest - See the article for more information and details.
