Wash 1 cup of rice and combine it with 1 cup of water, the sliced rib eye steak, fresh broccoli, sliced white onion, soy sauce, dark soy sauce, sesame oil, sugar, oyster sauce, and garlic powder in a rice cooker or suitable pot. Mix all ingredients thoroughly. Cook on the "white rice" setting or your regular cook settings until the rice is done and the steak and vegetables are cooked through. Serve the dish hot, topped with toasted sesame seeds and chili crunch.
