Cook the rice to pack instructions. Drain and set aside.
Meanwhile, heat the oil in a large wok or frying pan, add the peppers and onion and stir-fry for 5 minutes.
Stir in the curry paste and sugar and cook for 1 minute until fragrant. Pour in the coconut milk, bring to the boil and simmer for 5 minutes until the liquid is reduced by a third.
Add the green beans and chicken and cook gently for 5 minutes, until the chicken is piping hot.
Divide the rice and curry between 4 plates and serve with lime cheeks and a sprig of coriander.
Jack’s tip: if you don’t have coconut milk in your cupboards, use yogurt and desiccated coconut instead. Yogurt can also help to cool down the curry if you don’t like it as spicy.
