Costco Hors D'oeuvre's ?
The Artichoke Dip is great so are frozen mini cheese cakes.
Cheese/vegetables Trays are good and you can always order some sandwich trays.
I haven't tried the vegetable spring rolls.
There is also a couple of frozen mix appetizer trays that are sold there but I haven't had those.
I just bought a bunch of stuff at Costco for New Years Eve and it was all pretty good.
Shrimp & Cotija Cheese Egg Rolls -Unique
Tempura Shrimp-Crisps amazingly in the oven.Tastes fried
Mini Quiches-Standard but decent
Potato Skins-Really Cheesy
Chicken & Pineapple Meatballs-I add Mr Yoshidas sauce into the crockpot with these.
Tillamook 100 anniversary cheddar sliced on those water crackers with a dab of Red Pepper Jelly on top-My favorite-I could eat Red Pepper Jelly on anything.
Everything was a hit-We didn't have any leftovers.
Frozen Meatbals in Crock Pot (Sauce:BBQ sauce and Pineapple Juice)
Artichoke Dip (serve warm) with Garlic Crostini (in bags)
Bruschetta with Crostini
Turkey Roll Ups - in Deli or Platters
Mozzerella wrapped with Proscuitto
Chicken Salad - can make mini sandwiches
Thought I'd respond to this old post as this month's Town and County has an article about creating wonderful hors d'ouervres using Costco ingredients. Event planner David Monn's ideas include: mini lamb chops coated w/ evoo, pistachios, kosher salt + p (broiled); mini corn muffins warmed and topped w/ kirkland pulled pork and jalapeno jelly; and shrimp marinated in lime and cilantro and garnished w/ avacado and carrot zest.
