I know TJ's carries different stock at different locations, and they can be priced differently too. I have long been a fan of the prewashed "southern greens" blend, which is always available at my TJ's for approximately 3.99 per package. I buy it and freeze it, because when I cook it the fact that it has been frozen does not affect the cooked texture or flavor. However, I do find that it's a bit pricey for a vegetable for basically one meal for two people.
This week, my TJ's started carrying prewashed, cleaned and cut kale for $2.29 per 10 oz. package. I was thrilled - it seems to freeze well too and I'm excited to use it in stir frys. Probably can't use it in salads, but if I flash fry it and mix with fresh cukes and sliced carrots and Zeff's peanut dressing I think it could be a good lunch option. Just wanted to share my find. For a dinner, I plan to sautee along with TJ's chicken mango sausage for a delish sweet/savory entree.
