Preheat a skillet, pan, or griddle to medium heat; about a five-minute wait.

Butter one side of each bread side.

On the opposite side, spread a thin layer of Thousand Island dressing.

On half of the bread slices, start layering with your cheese of choice, corned beef (to your desired thickness), and sauerkraut.

Top layered slices with a buttered slice of bread each, buttered-side facing out (to be pressed onto the pan).

Grill sandwiches on both sides until golden brown and serve hot.
