Sauté the Vegetables: Heat 1 tbsp of olive oil in a skillet over medium-high heat. Add the broccoli, mushrooms, and yellow bell pepper. Sauté for 5-6 minutes until the vegetables are tender but still crisp. Remove from the skillet, cover to keep warm, and set aside.

Cook the Chicken: In the same skillet, add the remaining teaspoon of olive oil. Add the cubed chicken breast and season with salt and pepper. Cook until the chicken is no longer pink in the center and is cooked through.

Combine Chicken and Vegetables: Return the vegetables to the skillet with the chicken, mixing to combine.

Prepare the Sauce: In a separate bowl, whisk together the soy sauce, chicken broth, sugar, sesame oil, and cornstarch until well combined.

Finish the Stir Fry: Pour the sauce over the chicken and vegetables in the skillet. Stir well to coat everything evenly. Continue to cook for an additional 2-3 minutes, until the sauce has thickened and clings to the ingredients.

Serve: Optionally, serve the stir fry over a bed of fluffy white rice for a complete meal.
