Transporting this dish is easy: Stack the fillet slices together and wrap them in plastic wrap; pack the arugula, onions, beans, and dressing in separate containers. Then toss everything together just before serving. Ingredients:
1/4 cup coarse-grain mustard |
3/4 teaspoon dry mustard |
2 1/4 teaspoons packed dark brown sugar |
3/4 teaspoon coarsely ground black pepper |
1/2 teaspoon finely grated fresh lemon zest |
1 (1-lb) trimmed beef tenderloin roast, tied |
1 tablespoon vegetable oil |
1 small red onion (1/4 lb), thinly sliced |
1/2 lb wax or green beans, cut diagonally into 2-inch pieces |
4 oz baby arugula (4 cups) |
1 1/2 tablespoons balsamic vinegar |
1 tablespoon fresh lemon juice |
1/4 teaspoon dijon mustard |
1/4 cup olive oil |
Directions:
1. Prepare beef: Preheat oven to 425°F.
2. Stir together mustards, brown sugar, pepper, and lemon zest.
3. Pat beef dry and season generously with salt. Heat oil in a heavy skillet over moderately high heat until just beginning to smoke, then brown beef on all sides, about 2 minutes total.
4. Transfer to an oiled shallow baking pan and coat with mustard mixture.
5. Roast beef in middle of oven until a thermometer inserted 2 inches into thickest part of meat registers 125°F for medium-rare, 15 to 20 minutes. Transfer to a cutting board and let stand until cool, at least 45 minutes.
6. Prepare salad while beef is roasting: Chill onion slices in water to cover 30 minutes. Cook beans in boiling salted water until crisp-tender, about 5 minutes. Drain beans in a colander and rinse under cold water to stop cooking, then transfer to a large bowl. Add arugula to beans. Drain onion slices and pat dry.
7. Make dressing and toss salad: Whisk together vinegar, lemon juice, mustard, and salt and pepper to taste. Add oil in a slow stream, whisking until emulsified.
8. Cut beef into thin slices.
9. Add onion slices, beef, and enough dressing to arugula and beans to just coat and toss to combine well.
10. Cooks' note: ·Salad components may be prepared 1 day ahead and chilled, separately.
