I'm planning a picnic for around 100 people. We will be grilling hotdogs & hamburgers with the fixins and I know I will have chips. What other sides are easy to serve, easy to prepare, that you don't have to worry about giving your guests food poisoning? The picnic will be late October in Oklahoma so it "should be" nice weather - not hot....but not cold. I will have some help....but plan on doing most of the work myself.
