When I know certain ingredients go together—in this case, fruit and cheese—I'm always tempted to put them in a sandwich. That was the case with this recipe, made with the leftovers of an arugula salad with pears (dressed with lemon and olive oil) and a wedge of brie. Why not put it all between two slices of bread and make it all melty?
Success is all in how you build it. It's essential to layer cheese directly next to the bread on both sides; as it melts, it fuses with the bread and acts as a barrier from sogginess. Next comes pear, so it has the chance to get fully warm, and finally the arugula, which will just wilt. Might sound like a lot of talk regarding a simple sandwich, but cooking is about the little things.
Other additions that wouldn't have been unwelcome: caramelized onions, a drizzle of honey, or a slice of good ham.
