Shopping at farmers markets is the easiest way to eat locally. You know where the food comes from: After all, the grower is right there and you can ask them. More than one shopper, however, has come home with bags of produce that went uneaten. And many others have left after a morning’s tour around the stalls only to go home with a bunch of carrots and a dazed expression. A bit of planning can keep weekly shopping for produce at a farmers market fun and make cooking a snap all week long.
