Prepare the Rice Noodles: Prepare the rice noodles by following the instructions on the package. Once cooked, drain them and set aside.
Cook the Chicken: In a large skillet or wok, heat 2 tablespoons of cooking oil over medium-high heat. Season the chicken strips with salt and black pepper. Add the chicken to the skillet and stir-fry for 5 to 6 minutes until they are golden brown and fully cooked.
Stir-Fry the Vegetables: In the same skillet, pour in the remaining tablespoon of oil. Add the sliced red bell pepper, chopped broccoli, and mushrooms. Stir-fry for approximately 3 to 4 minutes until the vegetables become tender yet remain crisp.
Add the Ginger: Add the freshly grated ginger to the vegetables and stir-fry for an additional minute to release the fragrance.
Prepare the Sauce: In a small bowl, mix the chicken broth, soy sauce, ketchup, and cornstarch until smooth.
Combine Everything: Return the cooked chicken to the pan, and add the cooked rice noodles. Toss everything together, ensuring the sauce coats the chicken, noodles, and vegetables evenly. Let it cook for 2 more minutes, allowing the flavors to meld together.
Finish with Sesame Oil: Drizzle a bit of sesame oil over the stir fry for added flavor.
Serve: Divide the stir fry among plates or bowls and serve immediately. Enjoy with your favorite garnishes like chopped scallions or sesame seeds!
