I first discovered Trader Joe's while attending college in Boston. This is a West Coast-based chain that had expanded eastward. Now there are locations in north Jersey (Bergen County) and Westchester County that allow me to indulge my cravings for the easy-to-make frozen dishes and affordable organic products sold here.
Trader Joe's shoppers are very loyal to this brand. Unlike other stores, you can purchase organics and other healthier food items at fair prices -- a big problem at mainstream grocery stores. Flash frozen seafood is a big favorite of mine, since I love to cook seafood but don't have the time to hit Hannaford or Price Chopper for fresh fish every night.
Ask any Trader Joe's shopper and they will likely have one or two favorite products they always buy at this store. I have many!
