Eat what's in season where you live.
The original Thanksgiving feast included some of the foods we eat today, like pumpkins and turkey (or at least wild fowl of various kinds), because they were abundant and in season in New England at that time. Try to include in your Thanksgiving feast what's in season where you live. The freshest and best-tasting food always is what's in season. The Natural Resources Defense Council has created a handy look-up so you can see what's in season in your state.
