I regularly read the Trader Joe's threads on Chowhound, and recently I saw a lot of people recommending the frozen fish curry. It costs a little more than some of the other frozen lunch options since it's fish, but it made for a nice end of year "treat" lunch.
Product name: Korma fish curry with basmati rice
Quick review: This was exactly as advertised, fish in curry sauce with rice, which meant that one of the big drawbacks for me was that it was a lunch without vegetables. But the dish itself was good - swai fillet in a curry made with onions, coconut milk, tomato puree, cashews, spices, tamarind, cilantro, garlic, turmeric, sesame seeds, coconut poppy seeds, fenugreek leaves, onion seeds, and bay leaves, with a side of basmati rice that was speckled with mustard seeds (and apparently curry leaves according to the ingredients but I didn't notice those). The flavor of the curry was excellent, the fish wasn't tough or dry, and it all worked well together. If there were some vegetables with it, then it would have been better, but they didn't misrepresent that on the box. It was 380 calories but felt more filling than the salad I ate the other day which had more.
Buy again? Yes. Probably not every visit, but once in a while as a treat.
