Cook the noodles: Bring a large pot of salted water to a boil. Cook the rice noodles according to the package instructions, usually around 5-7 minutes. Drain and set aside.
Sauté the chicken: In a large skillet, heat the sesame oil over medium-high heat. Add the sliced chicken thighs, season with salt and pepper, and cook for 5-7 minutes, until golden brown and cooked through. Remove the chicken and set it aside.
Stir-fry the vegetables: In the same skillet, add the broccoli, carrots, and red bell pepper. Stir-fry for 4-5 minutes until the vegetables are slightly tender but still crisp.
Make the sauce: In a bowl, whisk together the peanut butter, soy sauce, honey, rice vinegar, ginger, and minced garlic until smooth.
Combine everything: Add the cooked chicken and drained noodles to the skillet with the vegetables. Pour the peanut sauce over everything, tossing gently to coat.
Garnish: Stir in the chopped green onions and sprinkle with sesame seeds for added crunch.
Serve: Plate the sesame peanut chicken noodles and garnish with additional green onions and sesame seeds if desired.
Notes
Feel free to add more vegetables or adjust the sauce to your taste.
