In a small bowl, whisk together the soy sauce, Argo corn starch, chicken broth, honey, brown sugar, rice vinegar, and toasted sesame oil. Set aside.
Heat 2 tablespoons of vegetable oil in a large skillet or wok over medium-high heat. Add the cubed chicken and cook for about 5-7 minutes, or until the chicken is golden brown and cooked through. Remove the chicken from the skillet and set aside.
In the same skillet, add the remaining tablespoon of vegetable oil. Add the chopped green onions, minced ginger, and minced garlic. Sauté for about 1-2 minutes until fragrant, being careful not to burn the garlic.
Add the small broccoli florets to the skillet along with 3 tablespoons of water. Cover the skillet and steam the broccoli for about 3-4 minutes, or until it turns bright green and is tender-crisp.
Return the cooked chicken to the skillet with the broccoli. Pour the prepared sauce over the chicken and broccoli mixture. Stir well to coat everything evenly and cook for an additional 2-3 minutes until the sauce thickens.
Serve your Chicken and Broccoli Stir Fry over white or brown rice, garnished with sesame seeds if desired. Enjoy your delicious and nutritious meal!
