Help with potluck

So I live in a pg where my food and everything is already included so I don't have to cook. One of my friends is hosting a potluck and I need help with what I can take to his place?

His place is a lil far from where I live It will take an hour for me to go so I want something that will not go bad

I was thinking desserts maybe but idk what kind and if there's anything else that I can take
