I'm looking for ideas for something I can bring to a potluck on Saturday that will travel well and be unrefrigerated for several hours. It should be something that can be eaten at room temp, without benefit of warming up, and be a crowd pleaser. I'm tempted to go with a dessert or cheese plate, since that comes to mind as keeping well at room temp. However, I think the group might appreciate more a salad, veggie or main dish. Any ideas would be greatly appreciated.
