In a bowl, combine the chicken, 4 1/2 teaspoons of the soy sauce, and Asian spice blend. Toss to coat and let sit for 10 minutes.

In a large wok or saute pan, heat the oil over high heat. Add the chicken and stirring constantly, cook until brown, 1 to 2 minutes. Add the beans and stir-fry until wrinkled, stirring, about 2 to 3 minutes. Add the garlic and cook, stirring, for 10 seconds. Add the cashews, hoisin, remaining 3 teaspoons of soy sauce, sesame oil, sesame seeds, red pepper sauce and red pepper flakes. Stir to coat, and cook for 1 minute. Remove from the heat and serve immediately, over white or basmati rice. Garnish with green onions.
