If time is precious prior to that New Year's party you're hosting, ask guests to contribute an appetizer.
Most people are more than willing to share their favorite.
It's usually not much work for them, and it eases some of the preparation headaches on you. It generally works best to have mostly cold or room-temperature appetizers with just a few hot choices. These are some favorite hot choices, with most featuring convenient frozen puff-pastry sheets. When using puff pastry, work quickly because it tends to dry rapidly, turning brittle. That makes it difficult to work with and easy to tear apart.
