Ingredients

• 300 grams roast beef (sliced thin)
• 4 pieces ciabatta rolls
• 2 medium yellow onion
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 4 pieces provolone cheese (sliced)
• 4 tablespoons mayonnaise
• 2 teaspoons prepared horseradish
• 1 cup fresh arugula
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.25 teaspoon garlic powder

Directions

Step 1

Peel and thinly slice the yellow onions into half-moon shapes.

Step 2

Heat a large skillet over medium heat. Add 1 tablespoon of butter and 1 tablespoon of olive oil to the pan.

Step 3

Once the butter is melted, add the sliced onions, a pinch of salt, and black pepper. Cook, stirring occasionally, for 15-20 minutes, or until the onions are golden and caramelized. Remove from the heat and set aside.

Step 4

In a small bowl, mix the mayonnaise, prepared horseradish, garlic powder, and a pinch of salt. Set this horseradish mayo aside.

Step 5

Slice the ciabatta rolls in half and spread the remaining 1 tablespoon of butter evenly on the cut sides of the rolls.

Step 6

Toast the buttered ciabatta rolls in a grill pan or skillet over medium heat until golden brown and crispy. Remove and set aside.

Step 7

In the same skillet, warm the slices of roast beef for 1-2 minutes until just heated through.

Step 8

To assemble the sandwiches, spread a generous layer of the horseradish mayo on the toasted sides of each ciabatta roll.

Step 9

On the bottom half of each roll, layer warm roast beef, caramelized onions, a slice of provolone cheese, and a handful of fresh arugula.

Step 10

Top with the other half of the ciabatta roll, pressing gently to secure.

Step 11

Serve immediately while the cheese is still melty and the bread is warm.
