I love the idea of having the kids help pick and set up a veggie stand in the front yard. They could buy a treat with the money they raise.
Or just try to make the time and pick...and bring a basket or 2 to a local women's shelter. One thing foodwise so many shelters are lacking is fresh produce. They have the canned and boxed goods covered.
Then take as many veggies as you can and roast them in your oven. No oil, baking sheet at 400 until soft. Peel skins off and puree - freeze so that you can add to your kids' food (orange squash into homemade pizza sauce, acorn squash into mac & cheese, green beans into lasagna, tomatoes just bag appropriate portions for pasta/pizza sauces).
Lastly find out if your neighborhood has a blog...if so, post that neighbors can shoot you an email if they want to come and pick!
