Instructions

  1. Wash and dry all produce. Cut green beans into 1-inch pieces. Peel and mince ginger. Mince or grate garlic. Peel and cut carrot in thirds, then cut each piece in half lengthwise and slice into thin half-moons. Roughly chop mushrooms. Thinly slice scallions, keeping greens and whites separate.
  2. Whisk together soy sauce, stock concentrate, 1 tbsp hoisin sauce, sesame oil, 1 tsp honey and ¼ cup water in a small bowl.
  3. Heat a drizzle of oil in a large pan over medium heat (TIP: If you have a nonstick pan, break it out.) Add noodles to pan and toss until tender, 3-4 minutes. If pan seems dry, add a splash of water or drizzle of oil. Remove from pan and set aside.
  4. Heat a drizzle of oil in same pan over medium-high heat. Add mushrooms, carrot and green beans and cook until lightly browned and softened, 5-7 minutes, tossing occasionally. Add ginger, scallion whites and garlic and toss until fragrant, 1 minute. Season with salt and pepper.
  5. Reduce heat to medium. Add sauce and noodles to pan. Toss everything until well-coated and sauce has thickened slightly, 1-2 minutes.
  6. Divide lo mein between bowls. Garnish with scallion greens.

Recipe Tips

For best results, use a nonstick pan to prevent noodles from sticking.

If you prefer a spicier kick, add a pinch of red pepper flakes with the garlic and ginger.

Feel free to substitute other vegetables like bell peppers or snap peas.

Is this recipe gluten-free?

No, udon noodles and soy sauce contain wheat. For a gluten-free version, use rice noodles and tamari or coconut aminos.

Can I make this dish ahead of time?
