You must have a lot of veggies of your own if you don't want free veggies. In my neighborhood no one veggie gardens. And they all know that I do grow all those veggies. Especially the tomatoes and cucumbers. Before any veggies are ready fist thing in the season I have neighbors checking to make sure I have planted plenty of tomatoes and cucumbers. That way they know they all get their fair share.
And this year I have grown eggplant and summer squash for the first time ever. Believe me been eating a lot of grilled squash for lunches. And lots of eating of eggplant also. Plus giving some of both of those away.
