I usually try to make something that doesn't require oven space. We do quite a bit of pot-lucking and if several people need the oven it can get busy. When we potluck, usually the host makes the main dish and we all bring sides, appetizers, and deserts. I usually am requested to bring the appetizer because people like my artichoke dip or nage maki, or desert, of which I only do one, a trifle made with berries, cool whip, and angel food cake. Oh, and lots of booze.
I had a fun weekend a few weeks ago when my nephew (late 20s) called for a recipe for spinach dip (I'm known as the family cook). I didn't have one, haven't made it in years. But the guy is a pretty good cook when he tries, and so I just told him to make sure he uses frozen spinach and really, really squeezes it dry. Then I gave him a few suggested ingredients and method. He called back that weekend and several after and told me I'd made his (singles) life, that after that he'd been invited to more parties in a few weeks than he had in a few years.
So, it's an oldie, but obviously for handsome young single men, spinach dip works!
