- 8 ounces soba noodles
- ¼ cup soy sauce
- ¼ cup lime juice (from 2 limes)
- 2 teaspoons finely grated fresh ginger
- 1 teaspoon sesame oil
- ½ teaspoon light brown sugar
- 1 lb Hanger Steak or Skirt Steak, at room temperature
- Kosher salt and black pepper
- 1 tablespoon canola or grapeseed oil, plus more as needed
- 8 ounces baby bok choy, halved lengthwise if large (you could also use cabbage or brocolini)
- 1 cup julienned or thinly sliced carrots
- 3 to 4 radishes, thinly sliced (optional)
- ½ cup thinly sliced scallions (2 or 3 scallions)
- ¼ cup fresh cilantro, mint or basil, or a combination, roughly torn
- Flaky salt, for serving (optional)
Cook Noodles and Make Sauce
Cook soba noodles according to package instructions. Rinse under cold water, drain well and set aside. Meanwhile, in a medium bowl, whisk together the soy sauce, lime juice, ginger, sesame oil and brown sugar; set aside.
Sear Steak
Season the steak well with salt and pepper. Heat a large cast-iron pan over medium-high until very hot, 2 to 3 minutes. Add the canola oil and when it shimmers, add the steak and cook, undisturbed, until it begins to get crisp and golden on the outside, 3 to 4 minutes. (If you are using skirt steak, you may need to cut it into 2 or 3 pieces to fit in the pan, then cook for 2 to 3 minutes.) Flip and finish cooking, about 3 minutes more for medium-rare. Set aside and allow the steak to rest while you prepare the rest of the salad.
Cook Vegetables
Turn heat to medium and add the bok choy. Season with salt and pepper and cook, stirring frequently, until it begins to brown and char in spots, 2 to 3 minutes, adding another teaspoon or so of oil if needed to help if the pan is too dry. Remove from the heat.
Assemble the Salad
In a large bowl, toss the soba noodles, carrots, radishes (if using) and half the scallions. Drizzle with the ginger-lime dressing to taste and divide among plates or in serving bowls. Thinly slice the steaks against the grain and top each portion with some of the steak and the bok choy. Scatter the remaining scallions and the mint over top and season with flaky salt, if desired. Serve with any leftover dressing in a small bowl to be passed at the table.
