Boil the rice in a large pot with plenty of water for 15 minutes. When it is cooked, rinse in cold water and drain.
In a wok, heat the sesame oil and immediately add the ginger, garlic, and chilli. Fry for 2–3 minutes before adding the pepper, mushrooms, and corn. Stir-fry the vegetables for 5–6 minutes until they begin to sweat and soften.
