A richly flavored Korean style beef dish, served with rice
Whisk together onion, soy, sugar, garlic, sesame oil, sesame seeds, black pepper and cayenne in a bowl.
Cook meat and sauce in skillet over medium high heat. Stir until chicken is cooked and sauce reduces slightly, about 6 minutes.
(Watch saltiness. I have diluted with water and added cornstarch to thicken slightly.)
Serve with rice. Garnish with green onion and crushed red pepper. (I have served with noodles as well.)
