Creating Teriyaki Chicken Pasta Salad is straightforward if you follow these simple steps:

1. Cook the Pasta: Begin by cooking the pasta according to package instructions. Drain and set aside to cool.
2. Marinate the Chicken: In a bowl, combine the chicken breasts with 1/4 cup of teriyaki sauce. Allow to marinate for at least 10 minutes for maximum flavor.
3. Cook the Chicken: Heat olive oil in a skillet over medium heat. Add the marinated chicken and cook for about 6-7 minutes on each side or until fully cooked. Remove from heat and let it rest for a few minutes.
4. Slice the Chicken: Once cooled, slice the chicken into bite-sized pieces.
5. Prepare the Vegetables: While the chicken is cooking, chop the bell peppers, cucumber, and carrots. Set aside.
6. Combine Ingredients: In a large bowl, combine the cooked pasta, sliced chicken, and chopped vegetables.
7. Add Dressing: Drizzle the remaining teriyaki sauce over the salad. If desired, add rice vinegar for an extra tang. Toss everything together until well coated.
8. Season: Taste and add salt and pepper as needed to enhance the flavor.
9. Garnish: Sprinkle sesame seeds and green onions on top for added crunch and flavor.
10. Chill (Optional): For a refreshing taste, let the salad chill in the refrigerator for about 10 minutes before serving.
