Ingredients and Preparation

Before you start, ensure your leftover steak is well-rested and sliced thin. Here's what you'll need:

1 lb leftover steak, thinly sliced
2 tbsp olive oil
1 large onion, thinly sliced
2 cloves garlic, minced
4 crusty rolls
4 slices Swiss cheese
2 tbsp Dijon mustard
Salt and pepper, to taste
Optional: caramelized onions, sautéed mushrooms, or horseradish sauce for extra flavor

Cooking the Steak and Onions

Start by heating 1 tbsp of olive oil in a large skillet over medium-high heat. Add the sliced onions and cook until they're soft and golden, about 5-7 minutes. Stir in the minced garlic and cook for another minute. Remove the onions and garlic from the skillet and set aside.

In the same skillet, add the remaining 1 tbsp of olive oil. Increase the heat to high and add the sliced steak. Season with salt and pepper, and cook until the steak is heated through and slightly browned, about 2-3 minutes. Return the onions and garlic to the skillet and mix well.

Assembling the Sandwiches

Preheat your oven's broiler. Split the rolls in half and spread the Dijon mustard on both sides. Place the rolls on a baking sheet and toast under the broiler until lightly browned, about 1-2 minutes. Keep an eye on them to prevent burning.

To assemble, place a slice of Swiss cheese on the bottom half of each roll. Top with an even layer of the steak and onion mixture. Place the sandwiches under the broiler until the cheese is melted and bubbly, about 1-2 minutes. Watch closely to prevent burning.

Place the top halves of the rolls on the sandwiches and serve immediately. If you'd like to add extra toppings like caramelized onions, sautéed mushrooms, or horseradish sauce, now's the time.
