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.
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
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.
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.
