Cook the beans as per on pack instructions. Drain and set aside.
While the beans are cooking, start on the rice. In a large fry pan, heat oil and gently sauté onion for 5-6 minutes until lightly golden. Add capsicum and fry for 2-3 minutes and then add garlic and fry another minute.
To the pan, add rice, water, stock, crushed tomatoes, turmeric, oregano, salt and pepper. Bring to the boil, then lower heat and gently simmer for 30 minutes, stirring occasionally so the rice doesn’t stick to the bottom of the pan.
In another fry pan, heat oil and gently panfry the chorizo for a few minutes, then add the prawns and cook until they have changed colour and lightly golden.
To the rice mixture, add cherry tomatoes, green beans, cooked pinto beans, chorizo and prawns. Stir and let simmer gently for another 6-7 minutes until the green beans are tender.
