Browsing the boards as a midday procrastinatory excursion and read a thread from late October on good turkey sandwiches.
I'd like to add/recommend the turkey club at Grange Hall (50 Commerce St in the W. Village). This is an excellent sandwich with generous (but not gluttonous) layers of real turkey meat and good crisp bacon, LTmayo, etc., on lightly toasted thick-sliced bread. Most of the ingredients at Grange are organic - the turkey, too, I believe - and you can definitely taste the wholesome freshness of the food. I suspect they bake their own bread as well. Only drawback is the service is sometimes a little snooty - I'm not sure why, since the overall theme of the restaurant is of unpretentious class. But for a good lunch, this is hard to beat. They also offer a half-sandwich + soup or salad option which is a good value since the sandwich is very large and their soups and salads are quite good.
