What are the best party food ideas that I can serve to my up coming birthday?

As a 15 year old girl, every party I've been to it doesn't matter how much food there is the few things that are most popular are chips (any variety as long as there is some type of Doritos), chex mix, tons of pop and little candys (like a bag of Halloween candy). You can buy any kind of fancy fruits or cookies but the most popular would be the things i listed befor. Have a great party!
