Here’s an idea for something I call the “potluck club.” Invite six friends for dinner and share the menu beforehand: say, a Provencal barbecue featuring grilled butterflied lamb and a vegetable side dish, followed by a simple green salad with Camembert cheese on the side and a walnut tart with a bowl of berries. You, as host, will cook the lamb and pour the wine (a light Merlot is a good choice), and serve cocktails and coffee.
The rest of the menu is up for grabs. Give one of your guests the tart recipe, another the zucchini recipe. (If time or cooking insecurity are issues for your friends, there are always specialty food shops and bakeries.)
Pass out, too, the salad and vinaigrette, cheese, baguettes and the simplest bites to serve with drinks--roasted nuts, marinated olives or hummus with pita bread or crackers, all easily purchased. Talk these options over with your friends and see what interests them.
