Slice the flank steak into ¼ inch pieces against the grain. In a small bowl, combine soy sauce, honey, sesame oil, minced garlic, and ginger to create a marinade. Let the beef marinate for at least 10 minutes.

Bring a pot of water to boil. Add the rice noodles and cook for 3-4 minutes until al dente. Drain and rinse under cold water; set aside.

Heat a skillet over medium-high heat and add oil. Add the marinated flank steak and cook for 2-3 minutes without stirring. Flip and sear another minute then remove and set aside.

In the same skillet, add broccoli, red bell pepper, and scallions. Stir-fry for 4-5 minutes until the broccoli is bright green and tender-crisp.

Pour the reserved marinade into the skillet, letting it simmer for 2-3 minutes until thickened.

Add the cooked steak and drained noodles to the skillet, gently tossing for 4-5 minutes on medium heat.

Transfer to plates and garnish with sesame seeds and sliced scallions before serving.
