Heat a cast iron pan or skillet on Med. High
(I'm not a snob, it's just better this way. I don't know why).
In a small bowl, mix the Kraut with Russian dressing- just
enough to coat it, or to your personal taste. Set aside.
Butter one side of all four slices of bread (this is easier
to do if the butter has been out of the fridge for a while, or
softened in the microwave), and place two slices butter side
down on the pan.
Split the Kraut mixture into two equal portions and lay on
bread. Do the same with the Corned Beef, being sure to
separate the slices and folding them so the sandwich
is thick. Lay 2 slices of Swiss on each sandwich, and add
the top slice of bread, butter side up, on top.
With a spatula, lift the bottom of the sandwich and
check for goldenie-brownness. If it looks like it's super
yummy- flip it. If it looks just kinda warm, or slightly tannish,
leave it for another minute.
Once it's flipped, cook the sandwich for another minute or
two. A good way to time is to set out plates, drinks, chips,
and napkins while you're waiting. If you're sitting there
staring at the Reuben, you're going to take it off the
heat too early ('cause you'll want to eat it).
Once the flip side is goldenie-brown and the cheese
is melted, transfer sandwiches onto plates,
cut (diagonally) in half, place chips in between sandwich
wedges, and enjoy.
