Although, I really wonder if the word pie was the best choice in this case. "Pastry" would seem to be slightly more accurate to me, but I've petitioned for that coveted Trader Joe's product-naming position repeatedly over the past few years and have yet to receive a response, so what do I know?
The filling was very similar to the aforementioned spinach dip. And as was the case with the spinach dip, I definitely tasted spinach, but I really couldn't tell you if I tasted kale. Even after multiple dishes containing kale, I'm still not really sure if I know what it tastes like. That could be partly due to its blandness (but let's be kind and use the term "subtle flavor" instead). Or it may be due to the fact that kale and spinach are so similar in texture, flavor, and color, that it's completely pointless to put both of them into the same food together, except maybe to add a bit of exoticness to the name of the product. The only major difference between the spinach dip and the filling of this pastry is the absence of Greek yogurt in the latter.
With or without yogurt, spinach and kale would seem to be a healthy food choice. For a diet like mine, it might be a step in the right direction for the green roughage alone, but this particular item is chock full of sodium and saturated fat. The pie is pretty large, but not so large that a normal serving size is 1/6 of it. 1/4 of the pie seems a more realistic serving size to me, but you know how mathematically-creative people can be when drawing up the numbers for that Nutrition Facts column.
I think it's worthy of three stars. Sonia's going with three and a half on this one. Not bad.
Bottom line: 6.5 out of 10
