Menu Suggestions?

So I have decided to throw a little dinner party at my apartment this weekend with about a dozen of my friends in Paris. A lot of my friends are leaving to go home for Christmas at the end of next week and won't be back until January so this is the last weekend that we will all be in Paris together. I'm starting to wonder if everyone will fit in my apartment... haha, but I invited the people that I have spent the most time with here and that I'd like to spend a nice evening of wining and dining with. I've asked everyone to bring a bottle of wine and some sort of food item, but I think that I should maybe make some sort of main dish and I am wondering if there are any suggestions for something simple to make in large quantities. Let me know if you have any good ideas!
