Cooking for a Crowd

Hi Sisters,
We are going to use our Recipe blog as a place to post recipes "for a crowd" or recipes that easily doubled or tripled. These would be recipes for 20 or more. The sisters in our ward would use these recipes for preparing meals for InnVision, the shelter we provide meals for once a month or ward activities and other big events.
So please share your recipes {for a crowd} that you have been successful with and label how many the recipe would serve. Your talents will help us out so much!
