In a medium bowl, combine the sliced chicken breasts with soy sauce, sesame oil, minced ginger, and minced garlic. Marinate for 15 minutes.
In a large pot, bring the chicken broth to a simmer. Stir in the peanut butter, sriracha, and honey until fully combined and smooth. Set the sauce aside.
Cook the ramen noodles according to package instructions, usually about 4-5 minutes until al dente. Drain and set aside.
In a large skillet over medium heat, add the marinated chicken and cook for about 5-7 minutes, stirring occasionally until fully cooked.
Add the broccoli and red bell pepper to the skillet with chicken and cook for an additional 3-4 minutes until the vegetables are tender-crisp.
Pour the peanut sauce into the skillet with the chicken and vegetables, stirring to coat evenly for about 2 minutes.
Add the cooked ramen noodles to the skillet, tossing gently to combine everything well. Allow to heat through for an additional 1-2 minutes.
Serve immediately, garnished with chopped green onions, crushed peanuts, and fresh cilantro leaves.
