Loath as we are to suggest a leftovers-handling solution that involves creating a greater mass of food—the whole point of this is to get rid of the stuff in your fridge—fromage fort (French for "strong cheese") is the rare recipe-from-leftovers that really does turn assorted parts into a greater whole. It's flexible—nearly any cheese will do—and its short ingredient list means you won't need to make a separate grocery store run for any extra ingredients. Whizz together some cheese bits, butter, a skosh of dry wine, and some garlic for a punchy cheese dip / sandwich spread / pasta sauce waiting to happen. The more schizophrenic your cheese assortment, the better the dip: an ounce of blue here, a bit of aged goat there, some fresh chevre to smooth them out. Just keep your total number of cheesy additions to four of five so their flavors still ring true.
