Ingredients :
8 slices marbled rye bread
1 lb thick sliced corned beef deli meat chopped (I used the best quality available)
1 c sauerkraut drained
8 oz thousand island dressing
3 T fresh chives chopped
6 oz Monterey jack cheese shredded
6 oz Swiss cheese shredded
3 T butter softened
Instructions :
Preheat oven to 400°. Line a rimmed baking sheet with parchment paper.
Place 8 slices of bread on lined baking sheet and butter one side. Flip buttered side over so that it is facing down.
In a large bowl, combine all remaining ingredients.
Evenly divide Ruben mixture between the 8 slices of bread.
Spread the mixture so that it evenly covers each slice to the edge.
Place open-faced sandwiches in the preheated oven and bake for 20 minutes or until the cheese is melted and golden.
