This simple Beef Lo Mein recipe is made with flank steak, cooked vegetables and a simple soy sauce-based marinade. It's an easy, flavorful weeknight meal that's ready in about 20 minutes and tastes similar to your favorite Chinese takeout.
Start by whisking all of the sauce ingredients together in a small bowl and set aside. At this time, you should also start boiling water for the noodles, then cook them according to the package instructions. Drain and set aside.
While the noodles are cooking, heat 1 teaspoon sesame oil in a large, deep skillet over medium heat, then add the beef, sprinkle with salt and pepper and cook for 4 minutes or until it's done to your liking; remove from the skillet.
To that same skillet, add 1 tablespoon olive oil (or oil of your choice), then add the bell pepper, carrots, peas, and the green onion whites and sauté for 3-4 minutes until soft. Then, add the cabbage and garlic and cook for 1 minute.
Add the beef back into the skillet, along with the cooked noodles, and toss to combine. Turn the heat off, then pour the sauce into the skillet and stir until everything is coated with the sauce. Sprinkle with the remaining green onions and enjoy!
