Using a large skillet over medium-high heat. Once warm, add ½ tablespoon butter and allow it to melt before adding the 1 small sliced onion, 1 tablespoon sugar, ½ teaspoon salt, and ¼ teaspoon ground black pepper.
Cook the onion mixture stirring regularly until the onions are soft, translucent, and golden brown. About 10 to 15 minutes.
Carefully remove the skillet from the heat and stir in the 2 ounces corned beef, 2 teaspoons Worcestershire sauce, and 1 tablespoon mustard until combined. Set aside for a moment while you complete the next step.
Using 4 slices of bread, top each with a slice of cheese. Next, divide the corned beef mixture in half and place the mixture evenly on top of two slices of bread over the cheese. Cover the corned beef mixture with the other two slices of bread to create two sandwiches.
Using the same large skillet, return it to the stove over medium-high heat. Once warm, add the 1 tablespoon butter and allow it to melt before adding the sandwiches.
If the skillet is not large enough to hold them both at the same time, then divide the butter in half and cook them one at a time.
Once the bread has toasted on one side, use a spatula to flip to the other side and press the sandwich down using the spatula as it cooks.
Once the bread is toasted and the cheese has melted, carefully removed the sandwiches from the skillet and serve warm. Enjoy!

Use thick sliced Swiss cheese as it holds up better. If you prefer to use a different kind of cheese, try shredding it using a box cheese grater.
Select the right skillet! I love using a cast-iron skillet to make grilled cheese sandwiches because it holds heat evenly and well. A non-stick skillet is a good alternative.
Be sure to watch the heat and if you need to adjust it to a lower heat, then do so. You don't want your sandwich to cook too quickly and burn.
Make sure that you use enough butter to coat the entire bottom of the pan before adding the bread. Once you flip, if you notice that you need more butter than suggested, then go ahead and add it.
