Buy seasonal and local.
Go to the nearest farmer's market to stock up on tasty seasonal and local produce for your feast. Don't balk at the price of organic produce—instead, purchase organic items only where it counts. Apples, celery, grapes, lettuce, pears, potatoes, and spinach are some Thanksgiving produce items most likely to transmit pesticides to you. But if asparagus, broccoli, cabbage, corn, eggplant, peas, or onions show up in any of your recipes, it's OK to get these conventionally grown.
