Place the cashews on a baking sheet in a single layer.
Toast in the oven until fragrant, about 5 minutes. (They will crisp up as they cool.)
Preparing the Sauce
In a mason jar or bowl, mix together the rice wine vinegar, liquid aminos (soy sauce), sesame oil, ground ginger, garlic and chilli sauce. Set the sauce aside until needed.
Preparing the Casserole
Prepare a 9x13 casserole dish with nonstick cooking spray.
In a large skillet over medium-high heat, add the olive oil.
Season the chicken with salt and pepper and then add to the skillet in batches and brown on all sides.
Transfer chicken to the casserole dish.
In the casserole dish, toss the chicken together with the capsicum, broccoli, and onions.
Pour the sauce mixture over the chicken and vegetables.
Sprinkle over the cashews.
Cover and cook for 30 minutes. Remove the cover and continue cooking for 15 minutes.
