In the meantime, we were at Costco last week and saw this new item: Spinach and Egg Fettuccine Nests by Monte Pollino, made in San Francisco.

This might be a local SF Bay Area Costco product and possibly seasonal. It's a little more pricey than the standard Costco pasta, almost 3 times the cost actually since you can get almost 9 lbs of spaghetti for $9.99. If this were a regular product I would probably alternate between this and the regular pasta. Since it might be limited though, I'll be picking up another bag if I see it again next trip. :)
