Instructions

  1. Step 1: In a small bowl, mix 2 tbsp mayonnaise with 1 tsp prepared horseradish and 1 tsp Dijon mustard until smooth. Set aside.
  2. Step 2: Heat a skillet over medium heat. Butter 1 tbsp on one side of each of the 2 sourdough bread slices.
  3. Step 3: Place one bread slice butter-side-down in the skillet. Layer 6 oz roast beef slices, 2 sharp cheddar cheese slices, and 1/4 cup arugula leaves on the bread.
  4. Step 4: Spread the horseradish aioli evenly on the other bread slice, then place it aioli-side-down on top of the sandwich.
  5. Step 5: Grill the sandwich for 3-4 minutes per side until bread is golden brown and cheese is melted. Sprinkle 1/4 tsp black pepper over arugula before closing the sandwich.
  6. Step 6: Remove from heat, slice in half, and serve warm.
