In a medium bowl, whisk together the soy sauce, rice vinegar, honey, grated ginger, minced garlic, and sesame oil to make the dressing. Set aside.
Heat a grill pan or skillet over medium-high heat. Season the chicken breasts with salt and pepper, then grill or pan-sear for about 5-6 minutes per side, or until cooked through. Remove from heat and let cool slightly before slicing into strips.
In a large salad bowl, combine the mixed greens, shredded cabbage, shredded carrots, chopped green onions, and chopped fresh cilantro.
Add the sliced chicken to the salad bowl, then drizzle with the soy-ginger dressing. Toss well to combine.
Sprinkle the chopped cashews over the top of the salad.
Serve immediately and enjoy!
