The key ingredient of a successful spring bash? A relaxed host. Here’s how to create a store-bought spread that will keep you out of the kitchen and in the fun.

The Food

The Formula: Plan on serving approximately six bites per person per hour when no dinner will be served.

Total: That’s 180 bites for 10 people for a three-hour party.

Remember: It’s better to have too much food on hand than too little. You can always send your guests home with a doggie bag if there are leftovers.
