Ideas? Recipes? It's "potluck" but I think that there's less than a half dozen of us in attendance so "Mexican fiesta dip for 20" is overkill.
One idea I had was something chocolate. One person won't eat anything custard-like or anything with cooked fruit.
I prefer vegetarian but can work with meat if I make it myself. (Explanation: I prefer organic meat and have access to a suitable butcher but eating vegetarian is easier and cheaper.)
Tools at my disposal include a rice cooker and a Magic Bullet, if that helps.
