"A deli favorite, the best Reuben sandwiches strike a balance with a good helping of corned beef or pastrami, a bit of cheese, heaps of sauerkraut, and gobs of Thousand Island Dressing. You can serve a Reuben cold, but we love it toasted in a pan and served warm so that the cheese is melty and the dressing oozes out as you take a bite. What to buy: We like the strong, nutty flavor of Gruyère in this sandwich, but a high-quality Swiss cheese is more traditional.
