Fresh organic vegetables are incredibly expensive, but there is a brilliant way to get them entirely free. The ancient agricultural practice of gleaning allows volunteers to harvest the leftover crops that commercial farmers leave behind in their fields. Perfectly good produce is abandoned every year because they have minor cosmetic flaws or irregular shapes. Local charity organizations organize dedicated gleaning groups to rescue this valuable food before it rots in the sun. Let me explain exactly how this incredible system works and how you can fill your refrigerator with free farm-fresh produce.
