Cook corned beef in a slow cooker for at least 5 hours and then cooled for at least 2 hours. See how to cook corned beef here. If the corned beef is already cooked and cooled this recipe should take 45 minutes or less to make.

Slice cooked corned beef to desired thickness. To get that piled high sliced corned beef we use a quality tabletop slicer.

Place sliced meat in a fry pan or skillet over medium heat. Cook meat until warmed.

While the meat is still in the fry pan or skillet add a slice of Swiss cheese and cover with a melting dome until cheese is melted to desired texture.

Slightly toast bread.

Slather toasted bread with mustard. I just use regular mustard but use any type of mustard if you wish.

Using a spatula gently remove corned beef from fry pan or skillet and gently slide it on top of the mustard.

Add the other slice of bread on top. Slice bread using a bread knife.

Serve with potato chips and a sliced dill pickle.

Enjoy!
