Ok...here's what I'm looking for:
To bring to a BBQ (and actually grill)
Must travel well, advance prep ok
Vegetarian (but meat eaters must love it too)
Also to keep in mind, the other dish I'm bringing is a barbeque black bean succotash (black beans, corn, red pepper, onion). My usual staples to bring to these parties include veggie kabobs(they don't travel well enough for this one), portobello mushrooms, asparagus. (The mushrooms and asparagus are always a hit, but when the parties include the same people I have to mix it up a bit!).
