Cook the pasta according to the package instructions until al dente. Drain and rinse with cold water to stop the cooking process. Set aside.
Season the chicken breasts with salt and pepper. Cook the chicken on a grill or in a skillet over medium-high heat until cooked through, about 6-8 minutes per side. Once cooked, let the chicken rest for a few minutes before slicing it thinly.
In a large mixing bowl, combine the cooked pasta, sliced chicken, mixed vegetables, chopped green onions, and chopped cilantro (if using).
In a small bowl, whisk together the soy sauce, rice vinegar, sesame oil, honey or brown sugar, minced garlic, grated ginger, lime juice, salt, and pepper to make the dressing.
Pour the dressing over the pasta and chicken mixture in the mixing bowl. Toss until everything is evenly coated with the dressing.
Taste and adjust the seasoning of the salad with salt and pepper, if needed.
Divide the Asian Chicken Pasta Salad among four salad serving plates or bowls.
Garnish each serving with chopped peanuts or cashews and sesame seeds, if desired.
