I am putting together a reception, and planning to buy everything from Costco. I won't have chafing dishes, so everything needs to be either cold or, if hot, still palatable after it cools to room temperature. Want items that require minimal or no prep work.
What would people recommend? Shrimp, cheeses and nuts are already on my list. What else? FWIW, I have $200 to spend; not looking for sweets or alcohol.
