Instructions

  1. Bring a medium pot of salted water to a boil. Pat the steak dry with paper towels and thinly slice against the grain. In a medium bowl, combine garlic powder, half the cornstarch, half the soy sauce, a pinch of salt and pepper. Add the steak and toss to coat. Set aside.
  2. Once the water is boiling, add the noodles and cook until al dente, 5-7 minutes. Drain and set aside.
  3. While the noodles cook, prepare the vegetables: cut the tomato into ½-inch wedges. Core, deseed and dice the bell pepper into ½-inch pieces. Halve, peel and cut the onion into ½-inch-thick wedges. Trim and thinly slice the scallion greens; cut the scallion whites into 1-inch batons.
  4. Heat a drizzle of oil in a large nonstick pan over medium-high heat. Add the steak and cook, stirring occasionally, until a crust forms, 4-6 minutes. Transfer the steak to a plate and wipe out the pan.
  5. Heat another drizzle of oil in the same pan over medium heat. Add the tomato, bell pepper, onion and scallion whites. Cook, stirring occasionally, until browned and tender, 4-6 minutes. Meanwhile, in a small bowl, whisk together the sweet soy glaze, Sriracha, ketchup, stock concentrate and ⅓ cup water. Add the steak, noodles and sauce to the pan. Cook, stirring constantly, until the sauce thickens and the steak is cooked through, 1-2 minutes. Taste and season with salt and pepper if desired.
  6. Divide the lo mein between plates and top with scallion greens. Serve immediately.

Recipe Tips

For best results, slice the steak against the grain to ensure tenderness.

If you prefer less heat, reduce the Sriracha to ½ teaspoon.

To save time, prep all vegetables before starting to cook.
