In small bowl, combine 2 tablespoons water and 1 tablespoon xanthan gum. Set aside.
Heat 2 tablespoons olive oil in large skillet or wok over medium-high heat.
Place 1 pound chicken breasts into hot oil, then season with 1 pinch sea salt and 1 pinch black pepper. Add 1 zucchini, 1 red bell pepper, ½ cup carrots, ½ cup snow peas, and ½ cup cashews. Stir-fry until vegetables are tender and chicken is fully cooked.
Slowly add ¾ cup chicken broth, ¼ cup fish sauce, 3 cloves garlic, 1 tablespoon xylitol and 1 teaspoon sesame oil. Stir to combine.
Add xanthan gum mixture, stirring constantly until sauce thickens.
Garnish with Green onions and serve over cauliflower rice or with your choice of low-carb noodles.
