On a low heated skillet, lay buttered slices of bread down, butter side down.

Top each slice with pastrami sauerkraut and Thousand Island dressing.

Then place a slice of Swiss cheese on each sandwich. Top with another slice of bread buttered on the outside.

Turn up heat to medium/high. Grill sandwiches on one side until brown then carefully flip.

Cook on each side until cheese is thoroughly melted and bread is golden brown.
