I don't normally buy any prepared entrees at Costco, except the rotisserie chicken.
They were demo-ing these lamb shanks and I made the mistake of going Costco shopping hungry. Lamb is not high on my protein list, but the Household holds it in high regard. My sample was superb. I submitted to the siren call.
These are very good, lots of meat on the shanks, in our usage = 2 people 1 shank is a good meal. The sauce is great, there are the tiny fig seeds in it. Not cheap, ~$24 per lb.; each shank is pre-bagged so could be reheated sous vide. I used microwave method and it was very good. Any leftover sauce I'm saving for use in other dishes. Bones will go for a stock.
