Sweet, spicy, and savory Chinese five-spice powder gives this one-dish dinner robust flavor.
In wok or large skillet, stir-fry beef in oil over high heat until browned, 2 minutes. Add peas, bell pepper, scallions, ginger, garlic, and spice powder; stir-fry for 3 minutes. Add soy sauce, vinegar, and cornstarch; stir until saucy, about 1 minute. Serve over rice.
