Honey Mustard Chicken Stir-Fry

In a small bowl, whisk together the chicken stock, soy sauce, mustard, honey, crushed red pepper, black pepper and cornstarch. Set aside.

In a large skillet, heat 2 tablespoons of the olive oil. Add the chicken and stir-fry over moderately high heat until no longer pink and cooked through, about 5 to 7 minutes. Transfer the chicken to a plate.

Heat the remaining 2 tablespoons of oil in the skillet. Add the onion and stir-fry for 3 minutes, then add the garlic and cook for 1 more minute. Add the broccoli and stir-fry until crisp-tender, 3 to 5 minutes.

Stir the chicken stock mixture into the vegetables and cook until thickened, about 1 to 2 minutes. Add the chicken and stir-fry until heated through, about 1 to 2 more minutes. Season with additional soy sauce if desired.
