I made this with left over corned beef and it was delicious. This makes 2 huge sandwiches as written and I could only eat a half even though it was so good. Please judge your appetite and adjust accordingly!
Place 2 slices of the bread on a flat work surface. Spread one side of each slice with the Emeril's Russian Dressing. On 1 slice of bread, stack half of the cheese, ham, and corned beef in layers. Top with the other slice of bread, dressing side down, and push together to form a sandwich.
Spread softened butter on both sides of the sandwich and place in the hot waffle iron. Cook until the sandwich is golden brown on the outside and the cheese is melted, about 5 minutes.
Remove from the grill and cut into quarters. Serve immediately with the sauerkraut, and repeat with the remaining sandwich.
