I've mentioned it before, but
this cookbook rules. The chapters are organized by fruit/vegetable, so if you happen to get way too much okra, you go to the "okra" section and read about how to prepare it, whether it can be canned or frozen, and find a bunch of delicious okracentric recipes to use. It also provides information about the plants, including seasonality, how to how to plant and care for the crop, when to harvest, etc. This is useful if you are a gardener but also nice in a situation such as this where one might want to know when to expect a massive batch of beans to arrive.
Also, in addition to giving excess food away to neighbours and friends, you can also freeze and store some of the ingredients. If you have the room, invest in a small chest freezer and you'll have nearly fresh produce in the autumn and winter. Even though it's frozen, stuff from a garden still tastes ten times better than any frozen vegetable you buy at the store. It's also incredibly easy to do.
If you feel extra-adventurous, I'd recommend canning, especially with tomato sauce and a large batch of salsa. The tomato sauce is terrific to have for everything from lasagna to chili and there's nothing like cracking open a bottle of homemade salsa while watching a football game in December.
