Mix all the sauce ingredients in a small pan. Bring to a boil and then simmer for 5 minutes to thicken the sauce. Keep warm while you fry the chicken and cook the vegetables. Note: the sauce is enough to lightly coat all the chicken and vegetables but if you like your food swimming in sauce you will need to make extra.

Mix chicken in a bowl with the cornstarch to coat the chicken. Fry chicken in batches until chicken is cooked through. I used a small fryer and fried each batch for 1 minute with the oil at 360°F. I needed 5 batches. Set aside.

In a large skillet or wok add oil and heat up on medium high heat. Add in peppers and onions, and cook to just soften. About 5 minutes. Add in broccoli and cook for 2 minutes to heat the broccoli.

Add in the chicken and the sauce and mix to coat the chicken and vegetables.
