Begin by cooking the Asian style noodles according to the package instructions. Drain and set aside. Make sure to toss them with a little sesame oil to prevent them from sticking together.
In a large wok or skillet, heat the sesame oil over medium-high heat. Add the sliced mushrooms, red bell pepper, and green bell pepper. Stir-fry for about 4-5 minutes, until the vegetables are tender but still crisp.
Add the minced garlic and cook for another minute until fragrant. Then, stir in the cooked chicken breast pieces and season with salt and pepper to taste. Mix well to combine.
In a separate bowl, whisk together the chicken broth, low sodium soy sauce, brown sugar, Sriracha sauce, red chili paste, and minced ginger. Pour this sauce over the chicken and vegetables in the skillet.
Add the cooked noodles to the skillet. Using tongs, gently toss everything together until the noodles are evenly coated in the sauce and heated through. This should take about 2-3 minutes.
Remove from heat and stir in the chopped green onions. Serve hot, garnished with chopped peanuts for an extra crunch and flavor.
