Ingredients

1 1/2 pounds flank steak

Coarse salt and ground pepper

1 package (3 3/4 ounces) cellophane or bean-thread noodles

2 tablespoons vegetable oil

6 scallions, 3 sliced and 3 cut into thirds

1/4 cup fresh lime juice

1/4 cup chopped fresh, cilantro

1 garlic clove, minced

8 leaves Boston lettuce

1 ripe mango, peeled, pitted, and cut into strips

Preparation

Heat broiler, with rack 4 inches from heat. Place steak on a large rimmed baking sheet; season with salt and pepper. Broil until medium-rare, 10 to 12 minutes, turning halfway through. Let rest 10 minutes; thinly slice against the grain.

While steak rests, cook noodles according to package instructions; drain, and return to pot. Add 1 tablespoon oil and sliced scallions; season with salt and pepper.

In a small bowl, combine lime juice, cilantro, garlic, and 1 tablespoon oil; season sauce with salt and pepper. Fill lettuce leaves with beef, mango, and scallion lengths; drizzle with sauce. Serve with noodles.
