Cook the Noodles: Start by boiling a pot of water. Once boiling, add the rice noodles and cook according to package instructions until al dente. Drain and set aside.
Marinate the Beef: In a bowl, combine the sliced beef with hoisin sauce, soy sauce, and a pinch of salt and pepper. Let it marinate for about 15 minutes.
Stir-fry the Aromatics: In a large skillet or wok, heat the sesame oil over medium-high heat. Add minced garlic and grated ginger, sautéing until fragrant (about 30 seconds).
Cook the Beef: Add the marinated beef to the skillet and stir-fry for about 3-4 minutes until browned and cooked through. Remove from the skillet and set aside.
Stir-fry Vegetables: In the same skillet, add sliced red bell pepper and snap peas. Stir-fry for 2-3 minutes until the vegetables are bright and tender-crisp.
Combine and Toss: Return the cooked beef to the skillet with the vegetables, then add the cooked noodles. Toss everything together gently, ensuring the noodles are well-coated with the sauce from the beef.
Final Touches: Stir in sliced green onions. Taste and adjust seasoning if necessary.
Serve: Divide the noodles into serving bowls and garnish with sesame seeds and fresh cilantro if desired.
Notes
Feel free to add other vegetables or adjust the sauce to your taste.
