They would need to survive at room temp for a couple hours and be somewhat elegant....
For ex, some of my faves are:
Insalata Caprese (fresh mozz, tom, and basil)
Roasted chicken or duck
Prosciutto, salami, etc
Artichoke/ hearts of palm/ bell pepper salad
Ravioli or other pasta with pesto or marinara
Sauteed zucchini blossoms or other seasonal veggies
Various dips -- tapenade, baba ganoush, etc
Cheese, pate, olives, nuts
Berries/ various desserts
Kind of stuck in a rut though, and would appreciate any new suggestions!! Must be easy to buy or prepare!!
