Heat 1 tablespoon of oil in a large skillet or wok over medium-high heat.
Add the chicken slices, season with salt and pepper, and cook until browned. Remove and set aside.
In the same skillet, add the remaining oil and stir fry the vegetables until tender-crisp.
Return the chicken to the skillet.
In a small bowl, whisk together soy sauce, chicken broth, and cornstarch.
Pour the sauce over the chicken and vegetables, stirring until the sauce thickens.
Serve hot with rice or noodles.
