Alright ladies and gentlemen.... I'm throwing a going away party for a buddy who is leaving after next week. I will be hosting 30 or so people over in a week, Thursday the 5th. I was thinkin doin some slow roast chicken and ribs. My buddy is a huge bbq dude. Any other suggestions for a good, semi-buffet style food that I can cook in pretty large quantity and not spend $$$$ on?

I thought about just snaggin some food from restaurants, but I'd rather cook because it's more fun and generally better!
