Here is a collection of party foods from the New York Times  that are as easy to eat as they are to make. Each can be produced in 20 minutes or less. Many can be served at room temperature. And none require a plate.
Most of these recipes are beyond minimalist: they never do in two steps what can be done in one, and they need no embellishment. As you scan these recipes for ideas, mostly think this: The ones you find most appealing are the ones your guests will like. Choose a few, spend an hour or two in the kitchen, and you’ll be in great shape.
