Bring a pot of water to a boil and cook spaghetti as directed on the packaging.

In a large pan, heat oil over medium high heat. Add steak and sauté until cooked through, flipping the steak as it cooks.

In the meantime, in a small bowl or jar, mix together the brown sugar, hoisin, sesame oil, ground ginger, soy sauce, and pepper. Set aside.

Add onions to the steak and continue cooking for 3-4 minutes or until onions are soft and translucent.

Add carrots and sauté for an additional 2-3 minutes. Add cooked noodles and sauce and stir.

Serve with hot sauce, if desired, and enjoy!
