Step 1: Cook the Noodles

Boil sweet potato noodles according to package instructions (about 6–7 minutes).

Drain and rinse under cold water.

Toss with a little sesame oil to prevent sticking.

In a bowl, whisk together soy sauce, brown sugar, minced garlic, and sesame oil. Set aside.

Stir-fry beef slices with half of the sauce until just cooked.

Remove and set aside.

Step 4: Stir-Fry the Vegetables

Add a bit more oil.

Stir-fry onions, carrots, and spinach separately or together until just tender but still vibrant.

Sprinkle with sesame seeds and serve warm or at room temperature.
