Let's cut to the chase. They were good, but not great. Not a big fat artichoke taste, which is something of a disappointment, as artichokes are my favorite veggie. The price was good, as is so often the case at Trader Joe's. I don't know where the receipt is so I can't tell you exactly how much. I think you would need a package per person if serving as a main course.
I prepared mine with butter and real parmigiano. I would avoid a richer sauce or a tomato sauce as they would overpower the flavor of the stuffing.
The package also gives intructions to stir often. Better to cover instead after they have reached a gentle boil so as not to risk breaking the shell. Drain well.
Worth a try.
