Perfect Reuben Sandwich is the absolute best, so tasty, and easy to make! This sandwich is packed full of corned beef, swiss, and a simple homemade dressing!
Heat a griddle pan or a large skillet over medium heat.
In a small bowl stir together the dressing ingredients until mixed and set aside.
Place the slices of bread in a single layer on a cutting board and butter one side of each pieces.
Flip the bread over so that the butter is facing down.
Spread about 1 Tablespoon of the sauce onto each slice of bread.
Layer two slices of the bread with a slice of Swiss cheese, some of the corned beef (about 1/4 of it), half of the sauerkraut, the remaining beef, and another slice of cheese.
Place the two buttered slices of bread, butter facing up, on top of the sandwiches.
Carefully place the sandwiches on the griddle or skillet and cook for 3-5 minutes per side until toasted and cheese is melted.
