Preparation

Step 1

Cook the sweet potato noodles al dente according to package directions in a large stockpot of boiling water. Transfer the noodles to a strainer, rinse with cold water until chilled, strain out any extra water, drizzle the noodles with sesame oil, toss until coated, and set aside.

Step 2

Combine the steak, soy sauce, and a generous pinch of black pepper in a large bowl, and toss to combine. Let the steak marinate for 5 minutes (or up to 30 minutes).

Step 3

Whisk all of the sauce ingredients together in a small bowl until combined.

Step 4

Heat 1 tablespoon oil in a large sauté pan over high heat. Add the steak and sauté for 4-5 minutes, stirring occasionally, until cooked through. Transfer steak to a separate clean plate, and set aside.

Step 5

Reduce heat to medium-high. Add the remaining 1 tablespoon oil and the onion. Sauté for 3 minutes, stirring occasionally. Then add in the mushrooms, bell pepper, carrot, and garlic cloves and sauté for 4-5 more minutes, stirring occasionally, until the veggies reach your desired level of softness. Stir in the spinach and cook for 2 more minutes, using tongs to toss the veggie mixture frequently, until the spinach has wilted.

Step 6

Remove pan from heat. Add the cooked noodles, steak, and sauce to the veggie mixture, and toss to combine.

Step 7

Give the noodles a taste, and season with extra soy sauce and/or black pepper if needed.

Step 8

Serve warm, garnished with lots of toasted sesame seeds and green onions.
