Begin by cooking the Asian-style noodles according to the package instructions. Drain and set aside, making sure to toss them with a little oil to prevent sticking.
In a large skillet or wok, heat the sesame oil over medium-high heat. This will add a wonderful nutty flavor to your dish.
Add the sliced mushrooms, red and green bell peppers, and minced garlic to the skillet. Sauté for about 3-4 minutes or until the vegetables are tender and fragrant.
Stir in the cooked chicken breast pieces, seasoning with salt and pepper to taste. Cook for another 2-3 minutes until the chicken is heated through.
In a separate bowl, whisk together the chicken broth, soy sauce, brown sugar, Sriracha sauce, red chili paste, and minced ginger. This sauce is what brings everything together.
Pour the sauce over the chicken and vegetable mixture in the skillet. Toss in the cooked noodles and stir until everything is well combined and coated in that delicious sauce.
Remove from heat and garnish with chopped green onions and chopped peanuts. Serve immediately for the best flavor and texture.
