Preheat the oven to 350°F. Drain the sauerkraut well and squeeze it dry with a clean kitchen
towel or paper towels. (NOTE: you want to get as much liquid out of the sauerkraut as possible.)
Place the sauerkraut in a medium-sized bowl and mix it with the Russian or 1000 Island dressing
and caraway seeds if using, and then set aside.
Cut the Hawaiian dinner rolls in half so you have tops and bottoms. Place the bottom portion of
the rolls, cut side up, into an 11×7 baking dish.
Add 4 slices of the swiss cheese on top of the rolls. Add the corned beef, followed by the
sauerkraut mixture. Add another 4 slices of cheese on top. Add the tops of the rolls on top of the
filling.
In a small bowl, stir together the melted butter, onion soup mix, and poppy seeds. Brush the
butter mixture on top of the rolls, use it all!
Cover with nonstick foil or spray foil with cooking spray. Cover the baking dish with the foil and
bake for 25 minutes.
Take the foil off and bake an additional 5 minutes until toasted and browned.
Cut, garnish with optional parsley, and serve with more dressing for dipping, optional.
