What are some yummy, easy appetizers to have at a party?

I need suggestions for some easy appetizers to have at my daughter's 1st birthday party. I'm just having regular hot dogs and hamburgers for the main, but I'd like some "snack-ables" too. Mostly for the adults, since the kids will be too busy in the bouncy castle to want to snack =) I was thinking deviled eggs could be a good one, but I'm drawing a blank for other things.
