A simple and tasty sandwich. I usually use a sandwich roll and add the meat until it looks good, lol.
- Whisk mayonnaise, horseradish and rosemary in small bowl to blend.
- Season dressing with salt and pepper.
- Spread bottom piece of bread with half of dressing.
- Top with roast beef, tomatoes and arugula.
- Sprinkle with salt and pepper.
- Spread remaining dressing on top piece of bread.
- Press bread, dressing side down, onto arugula.
- Cut into 4 pieces and serve.
