I don't have a Cosco but I do have a Sam's with many of the same type of items. In addition to the bulk cheeses (which freeze well), pistachios, and frozen chicken breasts/ fish, I found a frozen shrimp that is called "Big Shrimp". It is delicious. The big shrimp is butterflied larg shrimp already seasoned in a butter garlic sauce. You just pop the frozen shrimp on the bbq for a quick and delicious entree. And best of all...NO carbs.
