Ingredients
2
large boiling potatoes (1 lb total)
3
cups shredded wine-braised chuck roast
1/4
cup finely chopped shallots (about 2)
5
tbsp mild olive or vegetable oil
1/2
lb haricots verts or regular green beans, trimmed and halved diagonally
1
large head Bibb lettuce
6
cornichons (French sour gherkins), cut lengthwise into 1/8-inch-thick matchsticks
1/4
cup chopped fresh flat-leaf parsley
Directions
2.
Put oven rack in middle position and preheat oven to 400°F.
3.
Place potatoes on a 12-inch square of foil, then prick each with a fork and wrap in foil. Bake until tender, about 1 hour. (Potatoes are done when a small knife pierces centers easily.) Unwrap potatoes and cool slightly.
5.
Reheat beef in a small baking dish, covered, in oven or in microwave until warm. While beef is heating, whisk together vinegar, mustard, shallots, sugar, salt, and pepper in a small bowl, then add oil in a slow stream, whisking until dressing is emulsified.
6.
Steam beans in a steamer set over boiling water, covered, until just tender, about 5 minutes. Meanwhile, peel potatoes and cut crosswise into 1/4-inch-thick slices, transferring to a large bowl. Add hot beans to warm potatoes along with 2 tablespoons vinaigrette, gently tossing to coat.
7.
Line a platter or 4 plates with lettuce leaves and arrange potato mixture on top. Toss meat, cornichons, and parsley with remaining vinaigrette and mound on top of potato mixture.
