First step: In a medium size bowl, combine chicken pieces with the whipped up egg white and 1 tbsp arrowroot. Toss and set aside.
Second step: In another bowl, blend the sriracha with coconut aminos, sherry, vinegar, broth, sesame oil and 1 tsp arrowroot. Set sauce aside.
Third step: Heat the 3-4 tbsp oil in a wok or large frying pan over medium high heat. Add the chicken and stir-fry until it separates and turns white, about 10-15 minutes. Remove from wok and set aside. Fry nuts, maybe 3 minutes, then remove and set aside.
Fourth step: Stir-fry scallions, garlic and hot pepper if you like it spicy. After a minute add in the chicken and stir-fry for another couple minutes before adding in the sauce, heat through until thickened. Add nuts, then stir to mix and pour over your cauliflower rice!
