Ingredients

• 400 grams Roast beef (thinly sliced)
• 1 loaf Crusty baguette or sandwich bread
• 4 slices Swiss cheese (slices)
• 1 cup Arugula or mixed greens
• 4 tablespoons Mayonnaise
• 2 teaspoons Prepared horseradish
• 1 teaspoon Dijon mustard
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 tablespoon Butter (optional, for toasting)

Directions

Step 1

Start by preparing the horseradish mayo. In a small bowl, combine mayonnaise, prepared horseradish, Dijon mustard, salt, and black pepper. Mix until smooth and set aside.

Step 2

If using a baguette, slice it lengthwise and into 4 equal portions. If using sandwich bread, separate 8 slices. Optionally, lightly butter the inner sides of the bread for toasting.

Step 3

On a flat skillet or grill pan over medium heat, lightly toast the bread (butter-side down if buttered) for 1-2 minutes until golden brown. Remove and set aside.

Step 4

On the bottom half of each sandwich portion, generously spread the prepared horseradish mayo.

Step 5

Layer with thinly sliced roast beef (roughly 100 grams per sandwich), followed by one slice of Swiss cheese per sandwich.

Step 6

Add a handful of arugula or mixed greens for freshness.

Step 7

Place the top half of the bread over the assembled ingredients.

Step 8

If desired, return the assembled sandwiches to the skillet or grill pan and press gently for 1-2 minutes to melt the cheese slightly.

Step 9

Slice the sandwiches in half for easy serving. Serve immediately and enjoy!
