It's hard to bring something to a BBQ that people will like that's still simple and quick to throw together. Throwing a few bits to fruit onto a stick is pretty much as simple as it can get. And who doesn't like a rainbow! You can dress up that boring buffet table covered in potato salad and baked beans!
I'd like to see a crew of fashion designers work with a bunch of pastry chefs to design amazing desserts. We could mash up Project Runway and one of those Top Chef whatevers and make a kajillion dollars! I could see this as Betsy Johnson's entry for a super simple petit fours.
