Heat the vegetable oil in a medium sized, deep frying pan over a medium heat and add the Thai green curry paste. Cook for 1 min until fragrant, then add the yellow pepper and green beans and briefly fry.
Add the coconut milk and bring to the boil. Reduce the heat, cover, and simmer for 8 mins, then add the prawns, cover and cook until they are just pink and curled, about 3 mins.
Prepare the microwave rice (or other rice) and divide it between two bowls. Divide the curry between the bowls.
