Editor's note: You gaze longingly into the fridge, your mental capacities diminished by hunger. At first you see only a seemingly-disparate collection of ingredients: sliced meat, a few lonely veggies, some cheese, a bottle of mustard, half a loaf of bread. Then your neurons rally to gift you this thought: I can make a sandwich! The salvation of hungry fridge-gazers, sandwiches are also infinitely flexible, portable, and are good hot or cold.
