While you make a worthy case for cold leftover pizza, it's just something I never would have heeded before being stranded* in a dorm at gods-only-know-what-o'clock with nothing but refrigerated food.

Yes, cold leftover meats are delightful. Something about the cold, and occasional ice crystals, just brings out the flavor.

*Most colleges, I know, have 24-hour food shops within easy walking distance of their dorms for just this situation, but ours did not. The local Denny's had been ordered to close at midnight in order to cut down on drug deals in the vicinity.
