Cook the fettuccine pasta according to package instructions. Drain and set aside, reserving about a cup of the pasta water.
In a mixing bowl, combine sliced flank steak, soy sauce, honey, sriracha, garlic powder, and ground ginger. Marinate for at least 15 minutes.
Heat olive oil in a large skillet over medium-high heat. Add the marinated steak to the skillet and cook for about 5-7 minutes, or until browned and cooked to your liking. Remove the steak from the skillet and set aside.
In the same skillet, add the sliced red bell pepper and snap peas. Sauté for about 3-4 minutes until the vegetables are tender yet crisp.
Add the cooked pasta to the skillet with the vegetables, along with the reserved pasta water (add gradually to achieve desired sauce consistency).
Return the cooked steak to the skillet and toss everything together until well combined. Season with salt and pepper to taste.
Garnish with chopped green onions and fresh cilantro before serving.
Notes
Serve in a shallow pasta bowl, adding a sprinkle of extra cilantro on top for color and freshness.
