Great article from NW edible on gleaning. “Gleaning (also called scrounging) is the act of collecting leftover crops from farmers’ fields after they have been commercially harvested or on fields where it is not economically profitable to harvest. Some ancient cultures promoted gleaning as an early form of a welfare system..source.”
She sort of walks you through what she learned from a friend who goes gleaning. If there are fruit trees or bushes in you are perhaps this article can show you how to go about gleaning them, with permission of course. But if you can do the picking, possibly the neighbor would be okay with a jar of jam or a pie in trade. You just can’t beat the price of free food.
